As always, our aim is not so much to tell you what to buy, but rather to make you aware of options and to equip you to make savvy, well-informed choices. With this thought in mind, we open the Guide with four articles we think youll find useful:

Headphone Buying Tips from Playback (a short, sweet list of essential usability factors and performance parameters to bear in mind when shopping for headphones).

Choosing Between Over-the-Ear vs. On-Ear Headphones (a cogent discussion of the pros and cons of both popular headphone formats).

Choosing Between Open-Back vs. Closed-Back Headphones (a careful look at the benefits and tradeoffs of these two major design themes).

On the Horizon: New Headphones Headed Our Way (14 headphone manufacturers give you a sneak peak at soon-to-be-released new models).

Recognizing that many listeners want candid, professional guidance in sorting through available options, this Guide to address two important classes of headphones:

Noise-Cancelling Headphones (geared for listeners who

prize sound quality, but who require headphones with active noise-cancellation features that will enable them to listen in noisy and potentially distracting environments). This Guide includes expert reviews of seven active noise-cancelling models ranging in price from $200 to $400.

High-Performance, Full-size Headphones (geared for listeners who have made sound quality their highest priority, and who typically will be able to enjoy music in fairly quiet listening environments. Listeners seeking headphones in this class are often seeking sound quality thatapart from headphonescould only be achieved through extremely costly loudspeaker systems). This Guide provides expert reviews of 24 high-performance models ranging in price from $59 to $1499. As youll soon discover, there are excellent options to fit almost any budget.

We hope you have as much fun reading this Guide as we did preparing it, and that it takes you forward in your quest for better sound. Enjoy.

Chris Martens, Editor, Playback

Welcome to the Playback Guide to Full-Size Headphones. Interest in high-quality, high-performance headphones is growing fast and for all the right reasons. After all, great headphones arguably offer more musical enjoyment and sonic refinement per dollar than any other class of audio product, which may be why unprecedented numbers of audiophiles

and music lovers are making headphones their personal hi-fi systems of choice.

InTRODUcTIOn

searching for great Headphones lets you experience the thrill of the hunt...



As long-term Playback readers know, our policy is to treat all headphonesregardless of price or typelike the serious high performance audio components they truly are.

When we listen to headphones in the course of doing review work (or to consider as models we might want to buy for our personal use), there are certain points we typicallly consider and qualities we invariably look for. We would like to share these with you in hopes of helping you make good, informed choices that will, we hope, lead to years of musical satisfaction.

First, three Very important Questions to ask1. How will you power your headphones?Some of the headphones in this Guide can be powered directly from an iPod, iPad, iPhone or other personal digital music players, while other should ideally be driven by good, powerful, high-performance headphone amps (whether they are portable or desktop units). Before you make any purchase, ask yourself how you want to power your new phones. If, for example, you dislike the idea of lugging around a portable amp, then it doesnt make sense to look at models that require such amps. You get the picture.

2. Where will you use your headphones?Some headphones lend themselves to on-the-

go listening, while others do not. Similarly, some designs are suitable for use in relatively noisy environments, while others mostly intended for use in quieter listening spaces. Carefully think through your real-world requirements before making any final decisions, and make sure you pick a model that can fit the kind(s) of listening you hope to do.

3. How much performance do you really want?The standard answer to this question is as much as I can get, but in practice the question is subtler than you might think. Be aware that, in headphones as in sports cars, high performance can sometimes be a double-edged sword. Understand that the very same qualities that enable certain high-end headphones to reveal the subtlest aspects of recorded music can also make them expose even minor flaws in your ancillary equipment or music. Our point is to be careful what you ask for, because todays best headphones can be incredibly revealingfor better or for worse. Think that point over carefully as you weigh the pros and cons of different models.

about playback reViewsAs a general rule, Playback reviews are not written with a shootout mentality, in part because we believe that listeners are individuals who have different needs and musical preferences, so that typically, there is

Its important to ask yourself how much performance you really need, want, and are willing to pay for.



no one right choice or best product.Instead, we hope youll consider our reviews

as fact-finding missions where the goal is to explore the sonic character of each headphone under review, talk about the strengths and weaknesses of each model. In a broader sense, our reviews also aim to give readers an idea of what levels of performance can be achieved at various price points (though as you will soon discover there are exceptional performers in almost every price bracket).

EssEntial QualitiEs to look For

Tonal BalanceThe ability to produce smooth, evenly balanced bass, mids, and highs, with nothing exaggerated, and nothing left out. In particular, we look for neutrality; that is, the ability to faithfully reproduce the sounds captured in your recordings (for better or for worse) rather than imposing a particular sonic color or flavor on the sound.

ClarityAccurate reproduction of transient sounds and musical texturessuch as the sound of a pick on guitar strings, the shimmer of cymbals, or the subtle echoes or

reverberations heard within recording spaces. Details matter, so that we look for headphones that can resolve even the most subtle, so-called inner details.

DynamicsThe ability to reveal contrasts between loud and soft passages in music without audible stress or strain. Also, we look for headphones that can capture very subtle low-level variations in dynamic emphasis, such as the way a singer uses vibrato or momentary inflections to add impact to a particular musical phrase.

Comfort/FitDoes the headphone accommodate a wide range of listeners and fit easily on your head without applying too much (or too little) pressure? Does the headphone feel secure on your head, or does it perhaps feel as if it might slip off? Finally, does the phone enable you to relax and listen, or does it distract you (or make you feel claustrophobic) in some way?

IsolationSome people prefer phones that block out external noises, while others

like phones that let them hear household sounds (e.g., doorbells, phones ringing, family members calling out, etc.). To help you find models that will fit your preferences, well indicate whether the phones under review offer high or low levels of noise isolation.

$$$ValueAre you getting your moneys worth? Ask this question early and often, because high prices dont necessarlily guarantee the

best performance. Now more than ever we all appreciate products that deliver lasting value.

Dare to be DemandingDont stop looking until you find headphones that fully satisfy your personal standards for musical realism. After all, thats the whole point of choosing high performance headphones in the first place.

cHOOsIng BETwEEn over-The-ear and on-ear headphones

There is a saying in the world of photography to the effect that the best camera is the one you have with you. The underlying point is that if a camera is too big or too heavy and you leave it in your hotel room or your car, you cant take a picture at all, so all those fancy features go for naught. A similar thought might apply to headphones, modified to the best headphone is the one you have on. In the case of headphones, sound quality matters a lot, but so does usability. Lets compare on-ear and over-the-ear headphones with the latter in mind:

oVer-the-ear headphones generally oFFer: Better isolation from external sounds Higher comfort for the outer ear Greater security (less of a feeling that

the headphone might slide off) Potential sense of ear claustrophobia

(an unpleasant feeling of being shut in) Greater weight and size

on-ear headphones generally oFFer: Smaller size, lighter weight, andin some casesavailable, built-in cell-phone mics/controls Avoidance of ear claustrophobia Less pressure on top of head and around the ear Potentially uncomfortable pressure on the outer ear Lower isolation from ambient noise

Of course all of these parameters can vary quite a bit from headphone to headphone, but you may want to try several pairs of each just to develop a general sense of which are acceptable.

Sonically, it is quite hard to generalize about over-the-ear headphones compared with on-ear headphones. There are many makes and models of each, and manufacturers offer models with a variety of sonic characteristics. We would say that bass response is generally different between the two types, with over-the ear headphones more likely to deliver correct bass depth and weight.

Finally, we should consider that many on-ear headphones are designed to be driven by portable players or small amplifiers. By contrast, more than a few over-the-ear headphones are comparatively power-hungry and thus require robust headphone amps to sound their best.

cHOOsIng BETwEEn open-Back and closed-Back headphones

Experienced listeners generally feel that there are two major differences between open-back and closed-back headphones: sonic differences and usability differences.

usability diFFerences:Usability differences are fairly easy to characterize. Generally, open-back headphones allow more external sounds to pass through to your ears than do closed-back headphones. This should come as no surprise, since open-back models suspend

their intentionally thin driver diaphragms in enclosure frames that, by design, are open to your ears (on the inside) but also open to the world at large (on the outside). Noise permeability is an inevitable by-product of these designs. Closed-back headphones, by contrast, have solid plastic, wood or metal driver housings to help provide additional isolation from external sounds.

Like all generalizations, however, this one has its limits. Specifically, it is important to understand that the seal between the

headphone and your head can also a pathway for external sounds. Consider this: a closed-back headphone that fits loosely will offer no more isolation, and perhaps less, than an open back headphone with a good circumaural seal.

All of this matters because external sounds are noise sources. Those external sounds could come from office workers talking, urban street sounds, jet engines, studio musicians, or merely an HVAC system in operation, but in all cases noise is

noise. Whether it is obvious or subtle, noise is not only a distraction, but it also reduces your ability to hear low-level sounds as instrumental notes decay. This is not simply a matter of audiophiles splitting hairs, because noise can dramatically impede your ability to hear subtle sounds that would ideally help convey the vibrancy and ambience of the music. In addition, higher levels of background noise make it more likely that youll crank up the volume to restore a sense of dynamics, but at the risk of potential hearing damage.

sonic diFFerences:When it comes to sonic differences, two are commonly mentioned. Closed-back headphones are thought to sound more closed in and compressed, though we would hasten to point out that there is as much variation in this aspect of sound between models of headphones as there is between closed-back and open-back designs in general. Let your ears be the guide there.

Closed-back headphones also can have more resonant sounding bass. Generally this means youll hear more powerful but potentially less articulate bass, but In some designs it could mean the oppositei.e., more lightly balanced bass (perhaps as a way to camouflage the additional resonances).

Finally, we should note that all of Playbacks top-rated headphone designs are open-back

designs. This may be coincidence or it may be that open-back design is technically superior. It may also mean marketing departments are simply catering to customer tastes, knowing many headphone enthusiasts assume (or believe) that sonic differences generally work in favor of open-back designs. Whatever the reason, judging solely on overall sound quality, the best-performing headphones Playback has tested thus far are open-back designs.

Playback noiSe cancelling HeadpHone reviewS



Over a year ago Playback published a series of reviews of active noise-cancelling headphones, collectively called the Sounds of Silence, and one of our favorite models at the time was Audio-Technicas Quiet Point ATH-ANC7. Though it was neither the most expensive nor the most elaborate of the designs we sampled, the ANC7 represented one of those less is more scenarios where everything about the headphone just plain worked as intended, giving excellent levels of noise reduction and very refined sound without any fuss, bother, or superfluous gongs or whistles. From off-the-record conversations I had with manufacturers of competing noise-cancelling phones, I learned the Audio-Technica had attracted their attention, too (so that some regarded the ATH-ANC7 as a worthy competitive benchmark to try and surpass).

Now, however, Audio-Technica has replaced the ATH-ANC7 with an updated model called the ATH-ANC7b ($219.95) that is said to offer incremental improvements vis--vis the original model. Since the audio universe is littered with examples of products that supposedly offer improvements but that in fact sadly represent steps backward, I decided to withhold judgment until I heard the ANC7b in action. Having now lived with the new model for several months, Im pleased to report that it really does take meaningful steps forward from the original ANC7, yet with no increase in retail price and no sonic downsides whatsoever. In short, the ATH-ANC7bs motto could well be, All gain with no pain, which certainly works for me. And as with the original ANC7, the new model represents a simple, elegant

Audio-TeChniCA ATh-AnC7b Chris Martens

noise cancelling headphonesgo to: noise cancelling headphones | full-size headphones

overviewConsider this active noise-cancelling headphone if: you want one of the most sophisticated and musically satisfying noise-cancelling headphones on todays marketone that combines very significant levels of noise reduction with the kind of sonic refinement approaching the sound of todays higher-quality passive headphones.

look further if: you want the very highest levels of noise reduction possible (or perhaps multiple noise reduction algorithms each optimized for handling different kinds of noise) and are willing to trade away some of the Audio-Technicas sonic sophistication to achieve that goal. But that said, be aware that no other noise-cancelling headphone we have yet tried offers a better overall combination of noise cancellation and sonic excellence.



solution that works to deliver unexpected levels of quietude with genuinely sophisticated sound.

When you get right down to it, active noise cancellers have to balance a delicate and difficult design set of design tradeoffs. To remove background noises, they must produce sounds precisely calculated to cancel out environmental noises from without, while at the same time reproducing the finer points and nuances of well recorded musicall without skipping a beat. Its a tall order to fill, yet one that Audio-Technicas ATH-ANC7b addresses with rare grace and sophistication, which is what makes this headphone so special.

Features: 40mm drivers with neodymium magnet

structures. Headphone operates in passive mode in the

event of battery failure. Detachable signal cable means the

headphone can be used for noise reduction only.

Quiet Point noise-cancellation circuitry promises 20 dB of noise reduction, while reducing environmental noise by up to 90%.

Compact, fold-flat design that allows earcups to swivel in both vertical and horizontal axes.

Powered by single AAA battery with projected battery life of 40 hours.

sonic characterThe ATH-ANC7b improves upon the already very good sonic qualities of the original ATH-

ANC7 in several noteworthy ways. To supply some background context for my remarks, let me mention that I described the original model as offering a slightly warmer-than-neutral sound with a touch (but only a light touch) of midrange forwardness. By comparison, the ATH-ANC7b offers more neutral voicing with slightly deeper and more robust bass and more extended highs working to balance out the original designs midrange strengths. The result is a more evenly balanced sound from top to bottom.

As with the original ATH-ANC7, the ANC7b does a remarkably good job of capturing the sometimes very subtle distinctions between good, better, and best recordings, giving the listener insights into delicate textural and transient details in the music. Let me be very clear on this point; more so than any other noise-cancelling headphone that Ive yet heard, the ATH-ANC7b could pass for a high-quality passive (that is, non-noise-cancelling) headphone, which is saying a mouthful. The fact that it can deliver this kind of sonic sophistication while also eliminating tons of background noise is what makes the Audio-Technica so desirable.

Ive used the Audio-Technicas in a number of different environments, but would observe that they can seem almost revelatory in two very different settings: genuinely noisy environments, such as jetliners in flight, and seemingly quiet environments, such as the interiors of homes where the only apparent noise sources might be HVAC equipment in use or the soft sounds of a television in a distant room. In both cases, the Audio-Technicas

knock background noise levels way, way down, so much so that you may marvelas I have at timesover how much quieter and more relaxing things seem once the QuietPoint circuitry is engaged.

One very real improvement in the ANC7b involves its noticeably quieter amplifier circuit vis--vis the earlier ANC7. Of the original model I wrote that listeners could hear a faint bit of amplifier hiss when the noise cancellation/amplifier circuit is switched on. With the new model, that hiss is essentially gonea small touch, true, but one youll appreciate every time you use the headphones with volume levels turned down low.

musical eXampleOne of my favorite test records is Tim Ries intricate and exquisite Stones World The Rolling Stones Project, Vol. 2 [Sunny Side], in

which Ries and a brilliant cast of musicians create world music/jazz reinterpretations of some of the Rolling Stones greatest songs. A particular favorite is Ries explosive Latin take on Under My Thumb, which positively froths and sizzles with dynamic energy. What makes the track a tough test for any headphone is the fact that it combines densely layered instrumentation, complete with wildly syncopated Latin percussion and bass, a blistering horn section, rollicking keyboards, and vocals fairly dripping with attitude and machismo (as in, Yeah, Mommy, I got you where I want you/under my thumb.).

Most phones stumble on this track, at least to some degree, either making it sound

compressed, muddled, or indistinct, or perhaps all of the abovebut not so with the Audio-Technica ATH-ANC7b. It just wades right in and owns this track in all of its glorious dynamic richness and detail. The ANC7bs capture, for example, the elastic bounce of the bass and the slightly off-kilter rhythms (and counter-rhythms) of the percussion instruments that drive the song forward, while doing a spectacular job with the horn section. Indeed, brass instruments have that just right touch of bite as notes first begin, yet without any edginess or underlying glare. Best of all, the ATH-ANC7b seem to breathe with the music, letting the dynamics flow without exaggeration but also without any apparent compression. As a result, the Audio-Technicas make it easy to be drawn deep inside the musica claim not all noise cancelling headphones could make with a straight face.

comFort Factor/accessoriesThe ATH-ANC7bs come with a good mix of accessories including: a detachable signal cable, a -inch adapter, an airline adapter, a carrying case with built-in accessory pouch, and a AAA battery to get you started.

The ATH-ANC7b is light, compact, and comfortable, applying firm (but not overly firm) clamping pressures. Still, after about a 1 -2 hour listening session, you may find youre ready for a break. The earcups are on the smallish side, so that some listeners might find them just slightly confining, though I personally found them to be an almost perfect size.

competitiVe analysisOne of the other strongest competitors for a best of breed noise-cancelling design would be Sonys flagship MDR-NC500D digital noise cancelling headphone ($399.99), so that I felt it would make for an apt comparison with the ATH-ANC7b. Heres how I would draw the lines of comparison. The Sony uses a so-called Artificial

Intelligence system to select from among three different digital noise reduction algorithms to choose the one thats most appropriate for the listeners environment. This level of adaptability arguably makes the Sony the all-around champ when it comes to noise reduction (especially in tricky environments that have lots of low frequency

noise). Interestingly, though, the results achieved by Audio-Technicas much simpler QuietPoint technology do not fall all that far behind the Sonys.

The Sony offers two power options: a rechargeable onboard Lithium Ion battery, or an outboard conventional battery pack. While the Sony solution exudes a certain measure of techno-coolness, it is also inherently complex (given the outboard battery pack, whose wiring is surprisingly intricate, the charger for the Lithium Ion battery, etc.). By comparison, the Audio-Technicas single AAA battery seems a much simpler way to go (and you can easily stuff a few spare AAA batteries in the accessory pouch without taking up much room). SIn the Audio-

Technicas case, simpler is indeed better. In terms of sheer sonic sophistication

and purity, both designs are very good performers, but if push came to shove I would give the nod to the Audio-Technica because its sound seems more effortless, natural, and unforced, whereas there are moments where the Sony can sound just slightly processed in its presentation. Sonic purity is one of the hardest things for any noise-cancelling headphone to achieve, and it is one the ATH-ANC7bs greatest strengths.

bottom line:With the ATH-ANC7b, Audio-Technica has taken one of Playbacks favorite noise-cancelling headphone designs and made it even better, first by giving the ANC7b more evenly balanced and extended voicing, and second by fitting the headphone with an even quieter amplifier/noise reduction circuit. This is a delightfully simple and easy to use product that offers a great combination of effective noise reduction and sonic sophistication.

More than three years in development, the Beats by Dr. Dre Studio headphones are the result of a three-way collaboration between artist and producer Dr. Dre, Interscope Geffen A&M Chairman Jimmy Iovine, and the engineering team at Monster Cable. Described by Monster as high definition powered isolation headphones, the Studios have set for themselves the ambitious goal of providing a brand new level of headphone audio performance with extreme clarity, deep bass and full power which had been

lacking in conventional headphones. Do they succeed? In many respects they do.

Features 40mm drivers. Active noise isolation circuitry said to reduce

environmental noise by up to 14 dB. Detachable signal cable allows the headphones

to be used purely for noise cancellation. Mute button lets listeners temporarily suspend

playback to focus attention elsewhere.

sonic characterFrom the moment you first power them up, the Studios sound dramatic, exciting and evocativethough not necessarily accurate. To explain what I mean, lets look at what the Beats do with bass, mids, and highs in music.

For the most part the Studios bass is powerful and well definedjust what youd what. But as notes descend lower, the Beats begin adding an extra measure of va-va-voom low-end punch, whether the music calls for it or not. This coloration sometimes sounds exciting, but can also make music sound inappropriately bass-heavy at times.

In the midrange, the Studios have plenty of definition and clarity, but they tend to pull middle frequencies back in the mix, making them sound slightly subdued or withdrawn

relative to bass and highs. But higher up, in the upper midrange/lower treble region, the Beats reverse course and actually push higher frequency sounds forward in the mix. As a result the sounds of cymbals, guitar fingering and picking noises, high notes on pianos, and vocal sibilance fairly jump out of these headphones. While this treble boost initially seems to enhance clarity (and can potentially help enliven dull-sounding MP3 tracks), it also puts a bright, penetrating edge on higher quality recordings, which can prove fatiguing over the long haul.

The Studios offer a modest amount of noise cancellation (or powered isolation, to use Monsters term), but noise reduction isnt really this headphones strong point. Drama and excitement is.

musical eXamplesPut on The Lesson from bassist Victor Wootens Palmystery [Heads Up] and youll hear a jaw-dropping slapnpop-style bass guitar solo thats tailor made to show off the things the Studios do well. Wooten slaps low notes with the side of his thumb, creating profoundly punchy low-frequency thumps, then tucks his fingers under the basss high(er) strings and snaps them upward, releasing hard, bright, percussive counterpoint notes. Adding to the mix are bright handclap- and castanet-like rhythm accents. The whole song works because both the low bass notes and brighter accent notes fall in regions that the Beats emphasizes, and the effect is spectacular, though perhaps overly bright.

But listen to the opening of The Difficult Kind from Sheryl Crows The Globe Sessions

[A&M] and the downside of the Studios becomes apparent. The song opens with Crows voice accompanied only by an electric guitar, and through the Beats two things happen. First, the twang of the guitar becomes unnaturally aggressive, drawing attention

away from the vocals. Second, the overtones of Crows voice get pushed so far forward that, as she sings higher up in her range, her voice sounds progressively more imbalanced, strident, and shrill. The point is that the voicing of the Studios complements some tracks, but not others.

comFort FactorThe Studios large earcups and plush earpads make them super-comfortable, even for long listening sessions.

ease oF useThe Studios are extremely easy to use, and we found their easy-access Mute button a touch we wish other self-powered headphones offered. The iSoniTalk cable is a welcome feature for those who wish to use the Beats with music-enabled cell phones; its a feature that no other noise cancelling headphone in this Guide includes.

bottom lineThe Beats By Dr. Dre Studios sound dramatic and exciting, but not necessarily accurate. They can seem terrific one moment, but become somewhat overbearing the next, depending on whether their colorful voicing matches well with the track youve chosen. Because this headphones voicing is not neutral, I recommend a try-it-before-you-buy-it approach to see if the Studios characteristic sound suits your tastes on a broad range of musical material.

The Aurvana X-Fi is Creative Labs premier headphone, both for audiophile and noise-cancelling applications. Unlike most of the headphones in our survey, however, the Aurvana X-Fi not only provides switch-selectable noise-cancelling functions but also offers two other user-selectable sound enhancement modes. The first is the X-Fi Crystallizer mode that, according to Creative, restores the detail and vibrancy to your compressed music and movies through a process where highs and lows are intelligently

enhanced. The second is the X-Fi CMSS 3D mode that is said to expand stereo MP3s and digital movies into virtual surround sound.

Features 40mm drivers with neodymium magnets. Active noise cancellation circuitry said to

reduce environmental noise by up to 20 dB. Headphones can continue to function in

passive mode should battery power run out. Detachable signal cable allows the

Sonic resolution and detail are very good, too, though not quite best in class.

sonic characterBefore I discuss the Aurvanas signature sound, let me point out that its noise cancellation circuitry is simply first rate. In noisy environments this headphone is quiet with a capital Qas good as the best Ive ever heard.

Sonically, the Aurvana X-Fi is an accomplished all-rounder that offers wonderfully neutral voicing and a smooth, evenly balanced presentation that is easy to listen to for hours on end. The X-Fi also

provides very good levels of detail and clarity without ever sounding edgy, sterile, or artificially vivid. While the best competing models offer slightly deeper bass and more expansive highs, plus a somewhat greater sense of sonic purity, focus and resolution, the Aurvana can hold its own in all those areasand without adding impressionistic colorations.

I had mixed reactions to the X-Fi Crystallizer and CMSS 3D modes. As advertized, the Crystallizer mode adds a measure of extra bass punch and treble snap that can help perk up severely compressed or dull-sounding tracks. The tradeoff, however, is that the mode also tends to undercut the Aurvanas ordinarily smooth sound, making higher quality recordings (especially uncompressed tracks) sound artificially pumped-up and brash.

The X-Fi CMSS 3D mode struck me as more

of a gimmick than a genuinely useful feature. It imparts a spacey, phase-shifted, and slightly brittle-sounding pseudo-surround effect whose appeal quickly wears thinlargely because it robs the Aurvana of some of its characteristic smoothness and unforced clarity. My advice: Try out the CMSS 3D mode when youre in the mood for sonic novelties, but turn it off for serious music listening.

musical eXamplesStormy Monday from the late Eva Cassidys Live At Blues Alley [Blix Street] makes a perfect showcase for the Aurvana X-Fis strengths. The track has a hearty, energetic, recorded-before-a-live-audience feel that the X-Fis capture quite effectively. Two notable high points are Cassidys heart-wrenchingly intense vocals (which can, through some headphones, sound a little raw at times) and a blistering electric

guitar solo heard midway through the song (a solo that, though wonderful, can sometimes sound a little too blistering for its own good). But what impressed me was the way the Aurvana X-Fis caught the energy and punch of the performances while at the same time taming (yet not erasing) their occasional rough edges. The Aurvana X-Fi finds a sweet spot of sorts where it reveals the good qualities in well-made recordings while tempering the flaws in less-than-perfect tracks.

comFort FactorThough it is neither the lightest or smallest headphone in this survey, the Aurvana X-Fi is supremely comfortable thanks to capacious earcups and earpads that offer a just-right blend of cushioning and support.

ease oF use The Aurvana places all user controls (four switches and one volume control) on its right-side earcup. On one level this is convenient because it allows one-hand operation, but it also means the noise cancellation, X-Fi Crystallizer mode, and X-Fi CMSS 3D mode switches are packed side-by-side, which can be a bit awkward for the fumble-fingered among us.

bottom line:The performance fundamentals of Creatives Aurvana X-Fi headphones are excellent, with noise cancellation as a particular strength (this is a headphone Id want to have along on a really noisy plane flight). Core sound is smooth, rich and natural, though perhaps not quite

the last word in terms of resolving low-level textures and details. The X-Fi Crystallizer and CMSS 3D modes are, perhaps, an acquired taste; I did not find them appealing over the long haul, but I can see how others might.




In this review Ill take a look at Denons latest entry in the noise-cancelling headphone marketplacethe AH-NC732 ($300). Unlike many of the noise-cancelling headphones reviewed in this Guide, the AH-NC732 is a light, compact, on-ear model (most of the other competing noise-cancellers Ive sampled have been over-the-ear models).

The little Denon comes with a useful though by no means extravagant set of accessories, and while the AH-NC732 tips the scales at a feathery 5.1 oz., its soundas youll discover in a momentmost certainly packs a heavyweight punch

denon Ah-nC732

overviewConsider this headphone if: you want a light, simple-to-use, on-ear noise-cancelling headphone that offers very good noise suppression and sound quality, with a pleasing mix of clarity and neutral tonal balance tempered by a just-right touch of natural warmth. The Denons can collapse to fit in very small spacesor to be packed up in their compact carrying case (included).

look elsewhere if: you would prefer the somewhat different feel and potentially better acoustic isolation that over-the-ear headphones might afford. Also look further if you want a headphone that offers switch selectable sound enhancement or simulated surround sound processing modes.


Chris Martens



sonic characterDenons AH-NC732 is one of the better-balanced noise-cancelling headphones Ive encountered, combining much (though not all) of the clarity and sonic transparency of a headphone such as Audio Technicas ATH-ANC7b (reviewed elsewhere in this Guide) with the natural, uncolored tonal balance of a headphone such as Creative Labs Aurvana X-Fi (also reviewed in this Guide). Extreme highs are just slightly rolled-off, but not to a

terribly noticeable degree (in fact, I think some listeners would interpret those slightly subdued highs as freedom from edginess and glare). Two particularly appealing aspects of the AH-NC732 are its solidly weighted bass (some of the best Ive heard from an on-ear design) and its gentle, just right touch of natural warmth, which makes the headphone sound inviting and engaging. At 105dB, the Denons sensitivity is decent, but falls 4-5dB below that of the class leaders, meaning youll need to

turn up your iPod to get optimal output from these phones. But overall, the AH-NC732 offers a pleasing mix of virtues.

The AH-NC732s active noise cancellation circuit is quite effective, though I felt its on-ear design offered slightly less acoustic isolation (that is, the ability to block out rather than cancel out incoming noise) than some of the better over-the-ear models Ive tested.

musical eXamplePut on Split Window from jazz/bluegrass/country bassist Viktor Krausss debut album Far From Enough [Nonesuch] and the Denons will immediately reward you with a warm, rich rendition of the brooding and highly atmospheric track. Through the AH-NC732s Krausss opening acoustic bass solo has an appropriately deep, sonorous growl while the bass drum that provides a rhythmic foundation

for the song has near-ideal low frequency weight and punch. Later, higher percussion instruments join in, followed by Bill Frisells haunting electric guitar, which picks up and then carries the melodic theme, putting forth evocative lines that float like question marks above the bass and percussion commentary going on below. The Denons do a fine job of expressing the lush and sumptuous vibe of the track, and especially of expressing the soulful, melancholy lilt of Frisells guitar. But that said, the headphones also come up a bit short in that they cannot quite capture the finely filigreed treble percussion and guitar details and harmonics that can and should give this track an air of mystery, suggesting a giant, wide-open recording space. The good news, here, is that the AH-NC732s strengths are compelling and self-evident, while its shortcomings are relatively minor sins of omission.

comFort FactorThe AH-NC732s are extremely light, compact, and very comfortable, although the feel of on-ear headphones may not suit all tastes. The seal that the Denons achieved on my ears was good, but perhaps not quite as good as that of some of the better over-the-ear models Ive tried. The trade-off, of course, is that the Denons weigh roughly 2-3 oz. less than competing over-the-ear models doa difference you can really notice over time.

ease oF useThe AH-NC732 offers simple, foolproof, single-switch operation. There is also a back-up,

passive mode if battery power runs out, though I found that sound quality was much, much better when the phones were powered up.

bottom lineBecause its overall sound is well balanced and clearer than most, Denons AH-NC732 is easy for us to recommend, especially for listeners who will appreciate its compact, lightweight design. In particular, this Denon does a bet-ter than average job of cancelling out ambient noise while offering solid and well-defined bass and smooth, revealing mids.

My favorite coffee hangout and Wireless hotspot is in a college town and so attracts the raucous crowd youd expect. I like to go for a 16-oz. triple latte and then sit with my laptop and surf the net while I plug into my selection of iTunes favorites. But frankly, between Becky at the next table talking loudly on her cell about her disastrous date with Bernard and Mr. tattooed-and-pierced wanna-be rocker humming and, gasp, actually singing bits from his in-progress Goth-inspired downer song lyrics . . . well, it can be a bit disorienting, to say the least.

Thats why when Editor-in-Chief Chris Martens asked me if I wanted to evaluate JVCs HA-NC250 noise canceling headphones, I jumped at the chance. The blurb on the product box said the NC-250s cut out up to 85 percent of ambient noise. Wow, I thought: 85 percent less of Becky and Tattoo Boy. Sign me up!

By the way, youll want to check out the reviews in this section of

noise cancellers, including those from Audio-Technica, Creative Labs, Beats by Dr. Dre, Sennheiser, and Sony. In my opinion, the JVCs compare most closely with the Beats by Dr. Dre Studio headphones within this test group.

(The JVCs also work well with higher-end audio gear.)

look further if: you actually like listening in on loud conversations nearby. Also look further if you want more sophisticated earphone features, such as digital sound enhancement modes or more elaborate noise cancellation circuitry. (For digital enhancements, however, you can cheat by using add-on software programs such as iWOW.).


Arnie Williams



sonic characterIf you can visualize a smiley face (and who cant), you have a pretty good diagram of the frequency response curve of the HA-NC250. This headphone likes bass and it also gloms on to high voice and upper instrumentation. The middle frequencies, however, seem a little subdued. But even with this shortcoming (and many wouldnt necessarily call this a shortcomingespecially those whose tastes favor the frequency extremes over the middle ranges), the JVCs perform well in many application settings. For example, they win hands-down in comparison to standard earbuds for an iPod (I tested them with an iPod Nano; worth the price of admission alone if standard earbuds are your current iPod gateway). They also perform well with a laptop in the kind of noisy environments Im

used to inhabiting. I didnt take them on a plane ride (were in the middle of an economic downturn, dont you know), but Id venture to say that theyd do swell in cutting out your chatty neighbors life story while you tune in to the in-flight movie or audio selections. I also tested them with standard DVDs on my Macs video player, and they performed well in that environment, too, given that I live in a noisy household. For high-end stereophiles, however, pricier (and more neutrally voiced) earphones may be the way to go.

musical eXamplesDid you know that Dirty Harrys (aka Clint Eastwood) son Kyle is a talented jazz composer and skilled bassist (both standup, electric, and fretless electric)? I often use Kyle Eastwoods Paris Blue [Rendezvous] as a test disc because its content spans the enitre audio spectrum, and well, because I like it.

The ambling laid-back tune Sulferino has a nice cross-range medley of electric piano, fretless bass, and sax, with the whisper of brushed snare and cymbals underpinning the ensemble to make this track a good test for full-range headphones (and speakers). The electric piano has delicate runs in the middle range, the sax soars up high, and the fretless bass holds down the bottom end. The HA-NC250s handled the upper and lower extremes well, but less so the middle frequencies. And the whispers tended to get lost. Even so, I found myself listening to this track again and again and enjoying the experience each time.

Perla Batalla singing Bird on a Wire from the soundtrack of the Leonard Cohen tribute


DVD Im Your Man [Verve Forecast], is a nice test song for midrange frequencies. Batallas full-bodied alto, complete with a touch of vibrato edginess, evokes the kind of sadness Cohen meant for the song to convey when he wrote it. Ive heard that vibrato edge given more definition by other headphones. On the other hand, when Batalla soared high, as she does at the end of the piece, and when some of the higher chords of the simple guitar accompaniment came along, both the singers voice and the guitar chords rang true, helping to make the listening experience enjoyable.

comFort FactorThe ear pads of the HA-NC250s dont completely envelop your ears, which I like because it avoids that kind of sweaty, suction-cup feel you get with some phones. The soft foam pads allow extended use without pronounced ear fatigue and the headphones are so light you might forget youre wearing them.

ease oF useOnce youve assembled the NC250s, they couldnt be easier to use. But there is one small catch: the JVCs battery compartment is hidden beneath one of the earpads, meaning youll have to remove the pad every time you install a new battery. Getting the ear pad off the enclosure in order to insert the battery isnt for the faint of heart. OK, its not that bad, but enough of a challenge to deserve a mild ding in the ease-of-use category.

bottom lineThe JVC HA-NC250s are decent performers

and all that some folks may need, especially if most of their listening is done through an iPod or a laptop in noisy settings. In fact, the ability to fold the earphones flat and the nice reinforced case make them an easy product to transport unscathed into some bustling environments (think college kids gone wild). But if your musical tastes call for high levels of detail and definition, or more neutral tonal balanceespecially in the critical middle frequency band, then you may want to move up to a more sophisticated model, perhaps in a higher price range.

The German firm Sennheiser is a fierce competitor in all segments of the headphone and earbud marketplace and the PXC 450 is the companys flagship noise-cancelling model. From the moment you first unpack these phones you begin seeing and sensing various visual and tactile cues that remind you of their German heritage. Theres a certain fineness of fit and finish about the PXC 450sa precision in the way their ear cups fold out and click into position before usethat is reminiscent of the detail touches you might find on a fine German automobile. Whats more, the PXC 450s leverage Sennheisers NoiseGard 2 circuitry and wealth of know-how accumulated through decades of experience in building award-winning audiophile headphones. That said, the PXC-450 is also one of the most expensive noise-cancelling phones in this Guide. Does its sound justify its price?

Features Earcups provide patented adaptive baffle damping, while drivers

incorporate Duofol diaphragmsboth features said to enhance sound quality.

Proprietary Sennheiser NoiseGard 2.0 technology is said to eliminate up to 90 percent of environmental noise.

Headphones can continue to function in passive mode should battery power run out.

Detachable signal cable allows the headphones to be used purely for noise cancellation with no audio.

SennheiSeR PXC 450

overviewConsider this headphone if: you simply like objects that evince old-school Germanic precision, fit and finish. Also strongly consider the PXC 450 if you think youd enjoy a headphone that offers decent sound and good noise-cancellation capabilities in active or Normal mode, but that shifts gears when used in passive or Bypass mode to behave more like a serious audiophile headphone.

look elsewhere if: you want a headphone that sounds its best with noise cancellation circuitry turned on (frankly, the PXC 450 sounds best in passive mode). Also look further if you seek maximum bang for your bucks; though undeniably well made, the PXC 450 carries a premium price for what it is and does.

sonic characterWhat we have here, really, is a tale of two headphones in that PXC 450 exhibits two different sonic personas, depending on whether it is used with its noise-cancelling circuit turned on or off. Used with the NoiseGard 2 circuit turned on, the Sennheisers exhibit tonal balance that seems skewed in a subtle way, with bass that is somewhat recessed, mids that are about right, and highs that are just slightly too prominent. The net effect is of a headphone that offers bright, crisp clarity but that is lacking somewhat in terms of natural warmth and appropriate bass weight and punch.

But flip the NoiseGard 2 switch to its Bypass setting and a different sonic persona emerges. In a subtle but significant way bass comes forward in the mix, while highs pull

back just a bit, leaving you with sound that is better balanced and more musically rewarding overall. Unlike any of the other noise-cancelling phones in this Guide, the PXC 450 actually sounds better in passive mode than when its noise cancellation circuitry is turned on.

Noise cancellation is very good, but not quite up to the standards set by the best phones in this survey, in part because the NoiseGard 2 circuit allows a bit more high-frequency noise to come through than the best systems do.

favorite concert pieces) is the third movement of ORegans Triptych, entitled Tryptych III. From Heaven Distilled a Clemency. The composition takes an at once serious and yet joyous and enthusiastic look at our inevitable transition from the here to the hereafter, so that the choir and its accompanying orchestra simply swing on the piece. The Sennheisers did a fine job of presenting small treble details and textures that revealed the smooth, powerful unity of Conspirares ensemble singing, an area where the choir excels. But at the same time, the PXC 450s lost some of the desirable swinging quality of the piece, because their tonal balance undercut the propulsive thrust of the lower voices and strings, robbing the piece of vital energy.

On this track and many others, I felt the PXC 450s sounded better balanced (that is, richer and more full-bodied) once their noise-cancellation circuit was set to Bypass mode.

COMFORT FACTORThe PXC 450 is a relatively large headphone (the ear cups are bigger than most) with thick, cushy ear pads. I found the Sennheisers extremely comfortable, but I am a relatively big guy, which means the PXC 450s big ear cups werent a problem for me. I could see how individuals of smaller stature might find the Sennheisers a bit bulky.

EASE OF USEThe PXC 450s many flush-fit control switches and buttons look cool, but they arent easy to use from an ergonomic perspective. I would suggest that Sennheiser give the switches a

set of raised nubs so to make them easier to identify and use by touch alone. Finally, the NoiseGard 2 Normal/Bypass switch is buried under one of the ear cup hinges, meaning you have to take the phones off to access the switch; a more accessible location would be better.

BOTTOM LINEWe had mixed reactions to the PXC 450. The core, passive sound quality of the headphone is very, very good, but that sound quality took a subtle but audible turn for the worse once the NoiseGard 2 circuitry was engaged. The NoiseGard 2 circuit, for its part, does a good but certainly not state-of-the-art job of noise reduction. While the PXC 450s apparent build-quality is very high, I dont think that fact fully justifies the headphones steep asking price.

For starters the headphone offers true feedback-type noise-cancelling, where noise-sensing microphones are located inside the headphone ear cups, not on the outside as in most designs. This approach is said to yield superior noise cancellation. Sony uses a sophisticated DSP-driven system to compare audio and noise signals and then to apply noise filters and EQ as needed. Whats more, when the headphone is first powered up, an AI (artificial intelligence) circuit analyzes noise and then selects one of three available noise filters to achieve

optimal noise reduction for the given context. Add in high-tech drivers and amplifiers and youve got one of most advanced noise-cancelling headphones yet built, or at least thats the theory But how does it work out in actual practice?

Features 40mm dome-type drivers with neodymium

magnets. BTL (bridged transformer-less) amplifier is said

to produce a powerful sound with a wide dynamic range.

Unique feedback-type noise reduction system places noise-sensing microphones inside the headphone ear cupsnot on the outside as in


overviewConsider this headphone if: you want noise-cancelling headphones that can apply specific noise filters for different listening environments (airplanes, trains/buses, offices/study rooms). Also consider the MDR-NC500D if you seek a lively, highly dynamic sound, but with a certain amount of bass enrichment. Finally, check out this Sony for its its built-in, rechargeable Lithium-ion battery.

look elsewhere if: you seek optimally accurate tonal balance (the Sony puts out a little too much bass to qualify) or maximum clarity and transparency (the Sony is good in both departments, but some competitors do even betterand for less money). Note that there is some learning curve involved in figuring out how to tap the Sonys many advanced features.

most other noise-cancelling designs. The feedback-type design is said to be more effective and to have greater perceived impact than other, more traditional types of noise cancellation systems.

Sonys proprietary AI (Artificial Intelligence) noise cancellation circuitry, used in conjunction with DSP-driven equalization, is said to eliminate up to 99% of environmental noise. The AI system can automatically invoke, or users can manually select, any of three noise cancellation modes:

- NC Mode A (for use in airplanes), - NC Mode B (for use in buses or trains), or - NC Mode C (for use in offices or study

environments). Detachable signal cable allows the

headphones to be used purely for noise cancellation with no audio.

Headphones come with built-in, rechargeable Lithium-ion batteries (charger included), plus a back-up external battery pack powered by two AA batteries.

Monitor mode lets listeners temporarily suspend playback to focus attention elsewhere.

Control switches for headphone On/Off, AI On/Reset/Mode Select, monitor mode On/Off

accessories Gold-plated mini-jack-to-1/4-inch adapter plug. Airline adapter. Two detachable signal cables (.5M and 1.5M). AC charger for Lithium-ion battery. Back-up battery pack (2 x AA) with

detachable signal/power cable. Padded travel case.

sonic characterThis headphone offers a lively, expressive sound with serious dynamic clout, and it deliversover most of the audio spectrumpleasingly neutral tonal balance. The only deviation from accuracy occurs down in the bass region, where the MDR-NC500D consistently pushes low frequency notes too far forward in the mix (a characteristic some might enjoy, but others might find overbearing). The Sony offers good measures of clarity and detail, though it is narrowly edged-out in both respects by at least one other headphone in our Guide (namely, the Audio-Technica ATH-ANC7b). Noise cancellation in highly noisy environments is as good as Ive ever heard, but the MDR-NC500D also offers the benefit of being able to apply different noise filters for different listening contextsa feature no other headphone in this Guide offers.

musical eXamplesTim Riess Stones World [Sunnyside], as reviewed in Playback Issue 14, is a superb world music/jazz adaptation of some of the Rolling Stones most evocative songs and as such it makes a good test disc. One of my favorite tracks is the exuberant Puerto Rican rendition of Under My Thumb where a red-hot Latin rhythm section sizzles and drives the song forward with wildly syncopated beats. The Sonys do a great job with the track, partly because they cleanly delineate the voices of the various instrumentsespecially the percussion instrumentsand partly because they capture the unstoppable, locomotive-like energy and dynamic drive of the whole rhythm section. The only catch is that the Sony makes the electric bass and low percussion instruments, which play a big role in the mix, sound excessively prominent. Fortunately, this bass-forward characteristic isnt too distracting on Under My Thumb, but it sometimes can be on other kinds of material.

comFort FactorThe Sonys are light and compact, and provide a very good seal over your ears. The outboard backup battery-pack cable is a bit cumbersome to use, though, partly because the headphone end of the cable has two plugs (one to supply power, the other for audio signals) and partly because the 2 x AA battery pack is relatively heavy.

ease oF useIt takes a bit of learning to master the Sonys Monitor mode and On/Off switches (one is a

pushbutton switch, the other a slide switch), and especially to understand how to operate the multi-mode AI noise cancellation control. Be aware, too, that the headphone provides separate jacks for its audio signal cables and power/charging cables.

bottom lineSonys MDR-NC500D is a headphone Playback is proud to recommend despite its tendency toward a bass-forward sound, because it is in so many other respects a wonderful headphone. It is fun to listen to, sounds dynamically alive, is well-balanced over most of the audio spectrum, and offers much better than average clarity and detail. Throw in the fact that the Sony offers the highest-tech noise cancellation circuitry around, plus the convenience of rechargeable Lithium-ion batteries, and youve got a winner.

The AH-D1001s are among the lightest and smallest headphones in this Guide and for this reason are among the most comfortable. They are arguablyone of the few phones in this group light, compact, and sensitive enough to be worn comfortably outdoors and on the go. As it turns out, the Denons are alsoone of the least expensive phones in this sub-$200 group. Truth to tell, we originally requested Denons more expensive $350 AH-D2000, but that model was unavailable for review in our timeframe, so that the PR folks suggested we try the much less costly AH-D1001s instead. I worried, at first, that the little Denons might not be able to run with the big dogs, but they soon put my concerns to rest, proving themselves to be real overachieversand a very good deal.

Features: Light, thin, responsive 40mm micro-fiber driver

diaphragms. Earpiece design features an Acoustic Optimizer

said to adjust the sound pressure in front of and behind the diaphragm.

Driver motors feature neodymium magnets. Connecting cables that use oxygen-free copper

conductors.

accessories Soft fabric carrying bag. 1.7-meter extension cable with oxygen free

conductors. Mini-jack-to-1/4-inch adapter with gold-plated

jacks.

sonic characterThe AH-D1001s may not sound quite as big, revealing, or transparent as the top $200-$650 models,but they are so well-balanced you would never think of them as having shortcomings at all unless you compared them side-by-side with much higher priced phones. The Denons deliver a smooth, suave, sophisticated midrange sound supported by warm, nicely weighted bass. Highs are reasonably clear and extended, but trade off the Nth degree of definition and resolution in order to achieve a pleasing quality of natural sweetness.

musical eXampleThe Denons sounded downright seductive on Marilyn Mazur and Jan Garbareks aptly named Joy Chant from Elixir [ECM]. The AH-D1001s refined midrange did a great job of revealing the bouncing, exuberant sound of the steel drum-like percussion instrument highlighted on the track, while also giving Garbareks light, dancing sax lines plenty of room to play. While high percussion may not have quite shown as much treble detail and air as on the premium price phones, the presentation was still very satisfying. Beyond trying to reproduce the sound of instruments in a strict, accuracy-oriented sense, the Denons strive (successfully) to capture their overall feel or vibe.

But the Denons can really rock out, too, as I discovered when I put on Reckoner from Radioheads In Rainbows [ATO Records]. The track opens with a potent, expressive drum kit pattern that the AH-D1001s rendered with energy and snap. More importantly, though, they captured the songs giant, almost otherworldly soundscape, which gives the sense that the song is being performed in a garage the size of an Olympic gymnasium.

comFort Factor The light, compact AH-D1001s are among the most comfortable phones in this Guide. One small caveat is that their earpads are covered in a faux leather material that does not wick away perspiration the way fabric covers do.

bottom lineDenons AH-D1001 is a delightful headphone that combines sonic prowess with great versatility, comfort, and value. Though not a true top-tier performer in any one area, the Denons get close enough in all areas to make things interesting and at a more than fair price. One final point: the Denons are so easy to drive that, in a pinch, you could power them directly from an iPod (though only at moderate volume levels).
