Denon AH-NC732 Active Noise Cancelling Headphone Review

Denon AH-NC732 Active Noise Cancelling Headphone
Average Reviews:

(More customer reviews)
The Denon AH-NC732K is a very nice pair of headphones. They are compact, comfortable, and sound very good. The noise canceling works very well taking care of engine noise and other low frequencies. The included carrying case is perfect to slip in your briefcase or carry on bag and it has enough room for all of your adapters and cables.
The headphones don't fit around the ears like the larger Bose QuietComforts. They rest on and cover the entire ear. I was surprised that they were comfortable to wear. It took a little fiddling around to get a secure fit but it was worth it. The headphones feel like they are creating a seal to achieve maximum noise reduction. In fact if you just put them on without creating this "seal" you might not think much of these headphones so proper fit is key.
My first test was for noise cancellation. A lot of people will use these just for that feature and not even play any music through them. I ran an airplane noise WAV file through my desktop stereo system to simulate being in a plane. After cranking up the volume on my JBL 2.1 system I put the headphones on. There is a small switch on the side on the headphones to turn noise canceling on and off. With it off you could clearly hear the humming of the engines, the beeps of the seat belt indicators, and the general noises of cramming a hundred people in a cabin. Turning the noise cancellation on reduced these noises by 80%. The engines were barely audible and the beeps sounded like they were further away. Overall I was pretty pleased with the noise cancellation. Hopefully they work as well on a real flight.
I tested these for music with an iPod Nano and my stereo system. Plugged into the headphone out of my Peachtree Audio Decco using Sonos as a source I was immediately disappointed with the sound coming out of the Denons. They were bright and harsh with one note bass. I made sure the noise canceling switch was on, it was, and turning it off made the sound worse. I decided to "break in" the headphones before doing any more listening. I plugged them into the Nano and put it on shuffle mode, turned up the volume and then put a towel over them to drown out the sound.
After 5 hours of non stop playing I decided to give them another listen. They definitely sounded better, the highs were smoother and the bass was more relaxed. They still weren't great and for $299 they should be better. I decided to play around with the EQ settings on the Nano. Listening to The Beatles, Norah Jones, The Doobie Brothers, Daft Punk, etc. I checked every single EQ setting on the iPod. Surprisingly the Classical EQ setting sounded the best followed by Electronic , Rock, and Latin. With the Classical setting engaged these headphones sound fantastic. The volume was turned up 90% of the way to get the amount of sound I am used to, which is to say as loud as the real thing.
On my Shure E5C headphones the volume at half way is more than enough.
Comfort 4/5 They are very comfortable but it takes time to get them to fit correctly.
Convenience 5/5 I love the detachable cords, the case, and in a pinch you can listen to music if the battery dies.
Sound 5/5 They sound great once they break in but remember to try the EQ settings on your MP3 player to get the best sound.
Value 5/5 If you can try these at a local dealer and buy them for less than $299 (most dealers will discount) then they are a great deal, especially when compared to the competition.
EDIT 6-9-09
I took this set with me on a short flight from Denver to Milwaukee. Typically I take my Shure E5c ear buds, external headphone amp, and my iPod Touch with me on flights but I wanted to travel as light as possible on this trip. So I shoved the iPod into the back pocket of the Denons included carrying case and threw everything into my carry on bag.
So how much noise do they really cancel? Well I have to stick with my 80% comment from earlier. In terms of engine noise they probably canceled around 90%. It was the high pitched beeps, buzzing, and guy four rows ahead of me singing that got through.
I have always believed that in ear headphones like the Shures offered better sound and more isolation from noise than "noise canceling" headphones. Comparing my experience with the Shures and now the Denons I have to say that I have had a change of mind. These Denons were far more comfortable over the duration of the flight. They canceled more noise than the Shures blocked out and were less fatiguing to listen to. In a quiet environment the Shures E5C still has an edge over the Denon NC732 but my default travel headphone from now on will be the Denon AH-NC732.

Denon AH-D5000 Reference Headphones Review

Denon AH-D5000 Reference Headphones
Average Reviews:

(More customer reviews)
My perspective is a bit different:
Let me preface this review with a few points that should add to the review's credibility:
1. I am a classical sound engineer primarily, but work exclusively in acoustic genres where audio fidelity and sonic accuracy are paramount.
2. I work in both balance engineering and mastering, where I am often required to perfect the spectral balance (in both dynamic and frequency) of the final mixdown.
3. For over 10 years I have used Bowers and Wilkins loudspeakers in various environments (anechoic and otherwise) in addition to custom EQ'd headphones for my work. B&W is widely believed to manufacture the finest loudspeakers in the world.
4. I regularly attend live classical music concerts, often in ideal seating locations, resulting in a great familiarity of how live music sounds.
I researched a number of headphone options before settling on the Denon AH-D5000. I was curious about the Ultrasone models from Germany, but was wary of a technology that supposedly "corrected" cross feed and phase issues often experienced with headphones. The Denon frequency response curve was generally smooth, and any corrections could be made with a high quality EQ within the DAW.
There are immediately two things that are apparent when you first hear the AH-D5000. They require extensive burn-in. I have been listening to these headphones for approximately 5 days now, attempting to leave as much signal in them overnight as possible. There has been a very apparent change in their sonic character as related to frequency response throughout this period. I can tell you that burn-in is a very real requirement for those of us in the music recording business. Loudspeakers often are very rigid when new, resulting in a limited frequency response and higher than normal distortion-giving you that characteristic "hard", new sound. Headphones present the same challenge, and these Denons require significant burn-in. What appears to be happening over time is a reduction of deviation from a flat frequency response, resulting in a smoother curve as time goes on. I would not be surprised if these phones need at least 300 to 400 hours before they are finally settled.
They are bass heavy, but the curve is very smooth and easily correctable, and again appears to be smoothing out with time.
I knew they were something extraordinary however when I listened to the dynamics. I have never heard dynamic range so clearly represented. More specifically, I have never heard so many poor compression jobs, recordings where the engineers applied too much compression, inconsistently, at both low and high levels. You will actually hear varying degrees of compression used in individual tracks within the mixdown-astounding. You will also be presented with a soundstage that reflects EXACTLY what was happening during the mixdown process. When every recording you audition has easily differentiated characters of depth, compression, spectral balance, and soundstage, you know you have something that exhibits an uncanny level of resolution. I have never heard music so ruthlessly resolved in my life. NO speaker has ever done this for me.
I have to comment on driving these headphones. While for average listening to pop music with little change in dynamic range, you might possibly get by with a mediocre soundcard upgrade, these headphones require real amplification if you want to experience aural nirvana. I have auditioned them with various lower end amplification, and the result is always the same-a hardening of sound during high level transients. This disappears completely with better amping. Additionally, and I have never experienced this before in a headphone, I plainly hear changes in the character of the sound, particularly in soundstage and dynamics, when switching some audio plugins in and out of the mixer that are designed to NOT change the character of the sound. Specifically I'm referring to final stage limiting plugins that are intended to be transparent. Again, to have this so plainly demonstrated is just astonishing, and Denon deserves tremendous credit for this design. I can only guess this is due to the unusually thin transducers used (micro-fiber construction).
These headphones are sending back to mixes I have already done. Suffice it to say that my golden ears have just received a tremendous boost.
Finally, the construction. The mahogany is beautiful, the magnesium finish is of the highest quality, yet the phones are unbelievably light and comfortable.
I HIGHLY recommend the Denon AH-D5000. The listener must be patient with these though, as with regular use it may take up to weeks to get them to settle into their true character.Some further observations (Sun, 4 Jan 2009 20:55:54):
I have already mentioned the tremendous resolving power of these headphones. I would like to supplement on two points, amplification and general resolving ability.
It has become very apparent that these headphones demand the highest quality amplification. Wide spectrum music with tremendous dynamic range suffers terribly with anything but high quality power. You will immediately notice a "collapsing" soundstage and a reduction in the frequency response at the outer ends of the spectrum, with an earbleed quality pushing heavily around 3000hz. When auditioning, make sure you have clean, sufficient amplification.
I have researched a number a specifications for these headphones that clearly demonstrate their superiority. Particularly interesting are the impulse response graphs (available on the Headroom sight). These are some of the cleanest I have seen, and in comparison to other top end cans, are clearly superior. Headroom is overwhelmingly positive about these headphones, even alluding to the outstanding specs. No doubt these specs support my belief that these may be the most highly resolving headphones I have ever heard.
I'd like to add yet another observation. Tracking using a single mic vs. stereo mic during the mixing process is extremely obvious, particularly in multiple mic environments like those in symphonic recording. The monophonic tracks have a flat, airless, and overly focused quality to them in comparison to tracks that had the benefit of stereo microphones. Clearly this is something that Balance engineers will have to deal with as the mediums improve. Pop music engineers often use all their tracks in stereo, then adjust field and panning as necessary, resulting a very open, natural sound, granted sometimes to exaggeration. Classical engineers should really look into spot micing with pairs or stereo mics to really achieve a natural, open stereo sound. That said, all these characteristics are plainly obvious with these headphones.
For those of you interested, I have been researching and testing multiple EQ curves to get this headphone as spectrally accurate as possible. Please let me know if you would like these specs.
By the way, Denon has just released the ah-d7000, and by just about all accounts, it is substandard to the ah-d5000, yet almost twice the price. The preliminary specs show a more jagged frequency response with less extension on both ends, plus less accurate impulses. Get the ah-d5000 while you can.

Denon AH-D1100 Advanced Over-Ear Headphones (Black) Review

Denon AH-D1100 Advanced Over-Ear Headphones (Black)
Average Reviews:

(More customer reviews)
So I bought and compared these to my D5000's and D2000's...
The contrast when going from D5000/2000 to D1100 was pretty stark. I will break this down by "with" and "without EQ" because it's a big deal.
Without EQ adjustments- By default (without any EQ adjustments) I find that the highs are pretty good, though a bit rolled off in the highs compared to the D2000's and D5000's. To their credit, the treble never becomes uncomfortably sharp like the D2000s can, nor is the treble rolled off enough to make it feel dull or dark. I'd say we have about 92% of the D2000 highs here. The mids, however, seem arrested...by the bass. Indeed, I would describe the bass as somewhat overwhelming and can make some songs feel heavy and muffled. If I were to describe default the sound stage here I terms of positioning of instruments...I'd say the 1100's make you feel like you're sitting on stage (extremely forward; thinner ear pads than the D5000/2000) ...and within 2 feet of the bass (instrument) or the drums...and the other instruments / musicians positioned somewhere behind them. It's certainly not the organization you see in a performance. In Robert Glasper's piano performances, the piano sounds muffled. Dwele's R&B tracks sound a bit bloated/congested/stuffy. Denez Prigent's somber background tones in J'Attends sound muddled. Certain elements felt altogether missing in some of the classical and Bossa Nova songs because of that bass, principally. But other songs sounded good. Most of my Rock and Alternative also sounded either "not bad at all" or "pretty damn good" which was a bit unexpected. Staind for example, sounded great and Three Days Grace sounded pretty good. They really benefitted from the rich bass. So yea, some genres suffer...and sometimes just a couple of songs IN a genre (ie, R&B) suffer. HOWEVER, they are tolerable and if need be, you can certainly get used to them in most cases.
Also, for what it's worth, there wasn't a single track I threw at it that caused the low/bass reproduction to start clipping or distorting at all either on my computer or on my iDevices. This is impressive considering how much bass they hit with.* Strong genres- Pop, R&B, Hip-Hop/Rap, Alternative, Latin, Classical (w/o heavy cello/bass accompaniment), Rock (that doesn't feature a lot of low-cord "growl"), anything that could use a touch more bass
* Okay genres-Rock (with a lot of low-cord "growl"), Gospel, Bossa Nova, similar
* Poor genres- Jazz, Classical (with heavy cello/bass accompaniment), anything already on the edge of "bass saturation"With EQ on iDevices set on "Bass Reducer"or EQ or my computer with slightly raised treble and slightly reduced bass...
Yes. Oh yes. Bass now brought under control, it is now present and solid but not overwhelming at all. It's now similar in bass and arrangement to what we expect...though I still feel like I'm on stage (very forward). Drums and bass are now behind the other instruments. The reduction in bass allows the mids to actually be presented, though they don't extend quite as far as the D5000/2000, though they get close. Highs come out more as well, though they're still not as crisp or extensive as the D5000s/2000s (slightly recessed by comparison, maybe 96% of the D2000s treble range)...but nowhere near as far away either. All genres range from good to great. Sound stage is probably as wide as I could hope for. Bass feels more "thumpy" and more meaningful than the D5000/2000. Very impressive.

* Strong genres- All.
* Okay genres- None!
* Poor genres- None!

I think if the 1100's were my only cans I could afford, a little EQing will go a long way towards making me feel extremely satisfied with the purchase. If EQ adjustments aren't an option for you...or if those kinds of adjustments mess up the sound quality (depending on your portable device, it certainly can), you might find some genres/songs tough to accept with these cans. By default the D1100's are deep cans as-is and compliment some genres/songs who enjoy bass punch or have a perceived shortage of bass representation. For other genre/songs, look out. They have what equates to an 12" woofer in the car trunk, for good and for bad. Fortunately, it can be tamed and as such becomes mostly an asset. To be clear: we're talking about 3x - 5x the amount of bass when compared to the D5000/2000 at similar volume levels and flat EQs. There is enough bass to feel it on your ears even after hitting the "Bass Reducer" on your iDevice. Wow. Helluva driver. Maybe too much driver if you consider the D5000/2000 nearly too strong as it is.Scoring (no EQ): Highs 7 | Mids 6.5 | Lows 8.3 | Soundstage 7 | Clarity 7.7 | Comfort 8.5
Scoring (EQ'd): Highs 8.4 | Mids 8.1 | Lows 9.8 | Soundstage 8.25 | Clarity 8.75 | Comfort 8.5
Scores are written relative to my point of reference: my Denon AH-D5000's...which isn't necessarily a fair comparison (home cans vs. less expensive portable cans), but at least it's an objective commentary. These cans stand well above the V-Moda Crossfade, Beats, Bose On-Ear, Shure SRH840's and Senn HD555's. But be aware the bass is strong. If you're sensitive to too much bass, look elsewhere. If you love bass or don't mind taming them a bit with your EQ...they are winners.
Additional notes:
-They clamp pretty strongly to my medium-sized head but aren't uncomfortable.
-After wearing them for several hours a day for several days, I'm comfortable with saying you'll be fine wearing them for extended periods of time. I can see the relatively firmer pads softening up over time and becoming even more acceptable in that regard.
-There is no special wrapping on the cables. Just normal cables, not wrapped in fabric or anything. This is preferred for travel cans. You don't want stiff cables.
-Sound leak is minor. Much less sound leak than the AH-D5000's or D2000's.

Denon AHD2000 High Performance Over-Ear Headphones Review

Denon AHD2000 High Performance Over-Ear Headphones
Average Reviews:

(More customer reviews)
The Denon AH-D2000 is their second best model below the D5000 in this relatively new series of headphones from Denon, which isn't usually the first brand you think of when you mention "best headphones". But I think that is going to change now. This headphone is fantastic. As you may have noted in my other reviews, I'm not a stranger to nice headphones, spending thousands over many years trying different models (my version of my wife collecting shoes). My previous favorite, the AKG K701 (another $300 headphone) was my previous reference quality headphone but this headphone supercedes it. Whereas the AKG sounded more analytical and exacting, this Denon sounds more fluid and dynamic.
This headphone is a sealed design, so it doesn't leak or let in as much sound as open design headphones (which are most common type among the higher quality designs). It is SUPREMELY comfortable due to the well padded earcups and soft headband with a very light clamping pressure. Big-eggheads rejoice! It may feel a bit loose on those with smaller heads though, so you may want to try before you buy.
The sound:
Holy moly. This is the DO-IT-ALL headphone. Bass is deep and punchy, there is no mistaking that the bass is there, but not in a overbearing way. I compared the tonal balance of the bass to my home theater system which is flat (+/-3dB) down to a low bass limit of 23Hz. And these headphones present the bass in an accurate manner down to the lowest frequencies. It beats out the AKG K701 in that respect which always seemed to lack some impact in the bass. The highs are sparkly, clean and present. The crash of the cymbals are present, the sizzle of the high hats are there. As far as tonal balance, these would definitely rank up any of the other headphones short of the multi-thousand dollar sets. To me, this headphones gets the balance better than the Sennheiser HD650, AKG K701, any Grado, Beyerdynamic DT880 or 990, all the other contenders in this price range that are considered the top players. Soundstage (the positioning and sense of space of the sound) is very good too, expansive but with the sense that you are in a mid-sized venue, sitting about mid-way back. It's not as expansive as the AKG K701 in that respect but far better than a lot of other headphones. The mids are still well balanced with the highs and lows and never sounds disjoint. The highs are quite sparkly, but less sparkly and edgy than most Grado headphones, and nice detail without overdoing it. If you have recordings that sound bright, you may find this headphone does nothing to tame those recordings. But on reference audiophile quality recordings, you should find that these headphones are quite revealing. There are other headphones that might be better if you listen primarily to vocals, this headphone does justice to Dido, Diana Krall, the Carpenters very well. It worked well for jazz, trance, electronic, pop, rock, and orchestral music that I've tried. The sound is rich but yet detailed....the old cliche that you will hear things you never heard are applicable....I was literally pulling out my old recordings to hear stuff that I didn't notice in my previous AKG and Sennheiser models. Some people think the bass is a bit too loose and overpresent, but I think this is often a case of the music mastered as such. Heavy bass music such as trance will come across very strong, but this is no different than if you had a very deeply resolving subwoofer in a real speaker system. Compared to many other headphones, this headphone resolves way down to the lowest frequencies, and you are hearing what you can't hear at all with other headphones. The objective graphs show this, there is strong response down to 20Hz.
The only issue I have with the headphone is that the cord has a "TechFlex" type sheath which makes it very stiff, but it does increase its durability. Not a deal breaker in my opinion.
All in all, a solid FIVE star rating, no questions ifs or buts. You might be wondering if the more expensive D5000 at double the price is worth it. If you like the look of the wood cups and a tiny bit of refinement in the sound, and money is no object, you MIGHT want to consider the D5000, but it's a great example of diminishing returns. The D5000 cable isn't as annoyingly unruly as the D2000 cable, and is of higher quality though. If you want the best $300 headphone around, and are even willing to spend more, you should not overlook this choice. It's little brother model, the D1001 also takes top honors so you might want to check that one out if this one is too spendy.
This headphone is really meant for use for a home stereo, and if you use it with an iPod, the volume level is definitely weaker and may lack some punch. So I'd definitely recommend a separate headphone amplifier for that application. But otherwise, I was very happy with the sound of this headphone plugged into anything I could throw at it. If you have a first class system with high quality recordings, this headphone will really let you hear what you put into your system...it's revealing of bad sources, but yet somehow even lower quality MP3 recordings are still enjoyable due to its do-it-all versatility.
Sound quality: 9.5 out of 10
Comfort: 9.5 out of 10 (does get hot as all closed cup headphones do)
Value: 10 out of 10. Can't be beat in its price range
Build quality: 8 out of 10, some people report that the pivot screw comes loose after while....we'll see if this is still an issue. The headphone does look fragile due to the pivots, so I would be afraid to drop these.
These headphones ended my quest for the "one headphone" that I could happily live with for a long long time
Edit: after a couple of years, I ended up selling my D2000. I upgraded to the new D7000 model. You can read my review of that one. As well, I also have a Shure SRH840 which is a better headphone for monitoring because it blocked outside noise better than the Denons

Comply Tx-400 Foam Tips w/ Integrated Wax-Guard (Black) 3-Pair Pack Review

Comply Tx-400 Foam Tips w/ Integrated Wax-Guard (Black) 3-Pair Pack
Average Reviews:

(More customer reviews)
Great ear-bud tip replacements, sound wonderful and quiet -- super quiet.
That said, you are probably better off ordering them from the Comply website than here. I ordered these and they didn't fit in my ears. They would go in fine at first but then after a few minutes the foam expanded and caused pain. Checked the Comply website and there is actually 3 sizes (small, medium, large). Amazon only sends out medium. Granted, the Comply website does say that medium fits most ears. A way to check would be to try the 3 sizes of silicone ear-bud tips that you got with your headphones. Whichever one fits the best should be what you order. Perhaps worth mentioning is that medium silicone ones didn't cause any problems for me, they just didn't fit as well as the smalls. But medium foam definitely caused major problems for myself.
All that said, if you are pretty sure that medium will work for you, by all means order from Amazon.

Denon AH-D7000 Ultra Reference Over-Ear Headphones (Black) Review

Denon AH-D7000 Ultra Reference Over-Ear Headphones (Black)
Average Reviews:

(More customer reviews)
The AH-D7000 is the newest flagship reference headphone from Denon, a company usually known for their home theater electronics. Denon made a mark in the headphone market a couple of years ago when they introduced the AH-D1001, AH-D2000, AH-D5000 providing a well-rounded sound quality in the crowded market of premium headphone makers like Sennheiser, AKG, Audio Technica.
What I noted in my D2000/D1001 review is they are good headphones which have no glaring faults. They tend to have a very musically pleasing sound quality that doesn't dull the performance quality of the music, with their authoritative bass, clear and sparkly highs, but they don't overdo it either. They seem to do justice to most music types. So this "ultra reference" model carries on that tradition. The MSRP of this headphone is $999, and that puts it in the "ultra-expensive" category, but fortunately, you can actually find it discounted fairly steeply sometimes which brings the price down to earth a bit (but still orbiting). The main difference in this model over the lesser but similar wood-construction D5000 is an improved driver (higher efficiency) and a better finished wood earcup (now polished finish and nickel lettering that can't wear off). Looking at the spec sheets, there isn't much to differentiate it from the D5000 model to justify the $300 premium. Oh yes, but you do get a nicer box: A cardboard affair with leather-like panels, with a cloth material covering the main storage cradle. You don't even get an adapter to plug the ?" plug into the 1/8" jack of portable devices, which I guess sends the message, don't even bother using these with your iPod.
Ok, enough with the small talk.
Is this thing worth $1000? In many ways, no. On the surface, it's three times more expensive than the very competent AH-D2000 model which I reviewed and gave five stars to. For the extra money, you get a nicer box and the luxurious look of the polished wood cups. You get a less unruly cable which is stated to be of higher quality. But the headphone is still `Made In China', so it's not as if you are paying Japanese craftsmen descended from a long line of great Asian artisans to craft your headphone. The headband and swivel arm hardware is basically the same as far as I can tell. Even the ear pad itself looks and feels about the same. The difference between these and the AH-D5000 is even less apparent, as the D5000 is also made of high quality wood earcups. While you can easily justify that the D5000 costs more than the D2000 due to the solid wood earcups (rigidity is good to prevent resonances) the D7000 doesn't really seem to go much farther than the D5000 to justify that it costs almost 50% more. Besides the minor appearance differences, the only real tangible difference mentioned in the marketing blurbs is that the D7000 has a stronger magnet. If you try these headphones, you will find they mostly sound similar, the familiar sound signature clearly indicate that they are all from Denon, you won't be mistaking these for the warm polite sound of a Sennheiser, or the more clinical sound of some AKGs, or the energetic snappy bright sound of a Grado Labs model.
But hey, what are you REALLY getting in terms of the sound quality?
Since the D7000 has the same basic design as the D2000, I will say that they do sound similar in quite a few ways. The bass is strong and deep. Some people think the bass is too strong and uncontrolled, more of a flatulent sound than true accurate bass, but I disagree. The bass is strong to be sure, but I feel it's very well controlled. Maybe the fact that I have a big head helps, as these headphones are known to fit loosely, but on my head, they feel relatively stable and secure, but still supremely comfortable. But here's where one difference starts to be apparent as you compare the two. The D7000's bass quality is more punchy, more tuneful, seems to have no lower frequency limit, but still has good damping or control...like listening to a high end stereo system with a carefully manually equalized Velodyne DD-18 subwoofer that costs thousands. Whereas the D2000 has very good bass that is missing in some other brands' models, the D7000 takes it up a notch further. And then there are the highs, the D7000 seems to be more pristine, just slightly clearer and more detailed through, just a bit more sparkle overall. Again, these are pretty subtle differences overall, but they are there if you listen carefully, have a good system, and have good recordings that can highlight the differences. Other things like the soundstaging (placement of instruments/staging of the music) is pretty much similar; the D7000 has a richer, bigger overall sound in general
Where does that leave the D5000? The differences between the D2000 and D7000 can be somewhat subtle already, but the D5000 and D7000 are even smaller. I can notice that the D5000 does feel like a middle ground, the bass isn't as punchy or tight as the D7000, and the highs aren't as well controlled as the D7000. What does this come down to: I'll admit it, the D7000 is, like most higher end audio gear, a clear case of diminishing returns. You are paying a premium to get Denon's best effort, and luxury construction and presentation. The actual physical and engineering differences don't really reflect the price differential. The sonic differences are subtle for the most part, if I was blindfolded, I don't think I would be able to predict that I could identify which was which 100% of the time. But does that mean it's a waste of money? I would say no to that. If you take headphone listening seriously like I do, already spent good money building up a good system, a headphone like this just rounds out your listening experience. Even though it's diminishing returns to buy a headphone like this, I do appreciate that these do noticeably improve on the excellent D2000's which I loved and cherished for a year before I upgraded to these. Even though I describe the differences as subtle, I do appreciate the differences that I can hear.
Overall, these headphones has a completeness to the sound. The bass is indeed strong, and in fact, if you aren't use to listening to truly full range loudspeakers, you might find that these headphones do seem to go *way* over the top with their bass, and may seem to drown out the midrange compared to what you are used to. However, that doesn't mean I am implying that every other headphone is wrong and these are right though. If I was to try to analyze it, I think the D7000's do seem to go about 10-15% over the top with their bass and treble energy, but for me, it's erring on the side of offering a "fun" sound but without going overboard. I wouldn't master music with these headphones, but I'd still select these over many other headphones in their price range in terms of their overall musical accuracy. Every headphone has particular strengths and weaknesses. I do find these headphones are great for popular music, jazzy nightclub performances, electronic/dance, big band, but slightly less good for huge orchestral pieces (partly due to the closed nature, they sound a bit less 3 dimensional compared to the best open style headphones). As closed headphones, these don't leak that much sound.
So the bottom line is: for the most part, these headphones don't make any sense, but if your love of music runs deep, you like sound that is biased toward "fun" over purely clinically accurate sound quality, don't mind paying a bit more to get that luxurious look, then these are as good of choice as any other $1000 headphone that I can think of. The only other thing I should mention is that these headphones do have a very slight tendency to emphasize the upper midrange. Depending on the vocalist, there is just a tad bit of edginess to the voice. This could be a limitation of my system (as it usually is in most cases), but it's something to watch out for if you are sensitive to treble artifacts. All in all, the treble has a slightly more lively sound than average headphone I've owned over the years.
For the most part, I don't think I really want to try to convince anybody that these headphones are worth every penny, and that you shouldn't consider the cheaper D1001/D2000/D5000 models. You should because those are all great choices in their respective price ranges. I think these D7000's can compete against any other $1000 headphone, but like all things in the top 3% percentile pricewise, it's made for the fanatic or hobbyist that doesn't mind paying big dollars for the privilege of owning a top model to squeeze out that extra 3% of improvement. For the most part, I think the D2000 is a sweet spot and you should probably check these out first if you just want an enjoyable, excellent sounding, high quality, comfortable set of cans for general use.
