Product Description

Denon's AH-D2000 High-Performance Headphones offer two signature sound-enhancing technologies. First is the latest microfiber diaphragm technology. Microfiber's smaller size results in a denser diaphragmatic material which increases transmission rates for better sound and higher detail, affording maximum presence of acoustic sounds with low distortion. In addition, a special acoustic optimizer adjusts sound pressure balance on both sides of the diaphragm to deliver dynamic bass sound. The AH-D2000 includes a lightweight magnesium frame for maximum comfort during extended listening sessions, as well as aluminum connector covers, gold-plated connectors, and high-purity OFC cables.

Clean,warm, punchy bass, mid's and high's.
I will sum up by saying that these are the best sealed headphones I have ever listened to and I would buy them again if something happened to my current pair.
It worked well for jazz, trance, electronic, pop, rock, and orchestral music that I've tried.

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.

I have a pair of Shure in ear monitors (SE420s) and I needed something to use at work that did not irriate my ears after a few hours. I also have a pair of Sennheiser HD650s which sound exceptional but their sound leakage makes them somewhat impractical for use at work. I purchased these Denons and have not regretted the purchase whatsoever.

The AHD2000 have excellent clarity, detail, dynamics and are the most comfortable headphones I have ever worn. The bass response is a just a touch on the bloated side, but the headphones make up for it by accurately reproducing extremely low frequencies, possibly even lower frequencies then my beloved HD650s. The highs are not rolled off like there are with the HD650s or the Shures which can make some music a little fatiguing after awhile but for a lot of people the more accurate treble is a plus.

Another plus with the Denons is they are very efficient with a impedance of 25 ohms and sensitivity of 106 dB/mW so driving them with my Zune connected to the Zune dock at work leaves little to be desired. I have not listened to these extensively with a dedicated headphone amp so there might be a lot I am missing but I am happy with how they sound right now which works fine for now.

Before buying a set of Denon's I was using one of the higher-end AKG models, which are semi-open back design and sound very nice, but I was having problems with them comfort-wise; although a pretty light fit, some AKG earpieces are not big enough to fit clear around your ears -- they clamp your ears against your head a bit, which was really uncomfortable after a few hours. I'd heard a lot of great things about these, and I decided to pick them up because:

1. Comfort -- Big earpieces which fit all the way around your ears. The pads rest on your head, not your ears. Mine don't even touch my ears. Nice soft, thick letherette. Also the headband is really nice. Barely any pressure at all. One feature that might not work for some users is the shape of the earpads. They are ergonomically shaped very specifically to fit on your head a certain way. Putting these headphones on flipped around from the marked R and L feels pretty strange. They are very comfy and work for me, but you might want to try them on before buying. The way the pads are angled you really can't wear them with the headband in a lot of different positions. Once you get them settled though, wow are they nice.

2. A closed design. Although my AKG's do sound a little more "airy" and more like listening to good speakers in a room, they have quite a bit of bleed, both outside noise bleeding in and inside noise bleeding out. The ADH2000's do have more bleed than some other closed cans I've used, but outside noise reduction is decent.

3. Excellent sound. According to most of the reviews I'd read, these Denon's are among the best of the best closed-design, fullsize headphones. I was not disappointed. These sound ridiculously good. I really can not put them down.

Well, this is it. My long and beloved headphone journey has finally come to an end for the time being. I've been through many, and headphone after headphone failed to impress me in some aspect or another. I was beginning to lose hope in finding that "perfect" headphone for me. But then one day, I finally decided to purchase a MKIII. Now, I had to start all over again with trying out headphones -- or so I thought. I remembered two headphones that really stuck out from the rest of the bunch, and I wanted to get them both once more, not only to try them out with my new tube amp, but also compare them both side by side. So I bought the HD650, and a few weeks later, the D2000. Now, it's up to my ears to tell me which one will be my "perfect" headphone, and the one I will keep indefinitely.

My testing will be consisting of two systems. My first system will be my P1260 CD player hooked into my Little Dot MKIII with Slyvania 6AK5 tubes. The tubes and amp itself have well over 150 hours of burn in time. My second system will be nothing but directly plugging them into my iAudio 7 with a flat EQ and no sound enhancements. My HD650 has around 80 hours of burn in, although my D2000 probably only has around 30 hours, guesstimating low. Both headphones have not been modded in any way, shape, or form, excluding me stretching the HD650's headband for added comfort.

I find the only way I can get a truly accurate reading on a headphone is to compare it directly to another, side by side. Thus, I have both the HD650 and the D2000 with me right this second, and I will be doing extensive AB testing on a variety of music, at various volumes.
