Beyerdynamic DT 900 Pro X

This was, most certainly, not an impulse buy on my part but rather the result of a very long search for a good all-around open-back headphone, light and comfortable, with near reference sound quality (yet not overly analytical) and a reasonable price. Was that too much to ask for? Apparently not, since that search led me here: to the Beyerdynamic DT990-Pro-250. Now, for those who are curious (as I was) about that extra "AMS" label as seen here on this Amazon listing: the AMS stands for "American Music and Sound" - this is the US pro-audio distributor of Beyerdynamic. So the AMS is just an unnecessary marketing label - there is just one type of DT990-Pro, which is this one, regardless whether you buy it in North-America, Europe, Asia, etc. That aside, let me start off with the build quality: The DT990-Pro is made entirely of ABS plastic, save for the headband and the forks holding the cans, which are made of metal (aluminum, I'd say, from the weight of it). The head-band is covered with a soft black plastic material held in place by four small clasp-buttons. The DT990-Pro is surprisingly light and extremely comfortable (in this it rivals the other "most-comfortable" headphones I have here, the Sennheiser HD-598). Overall I'd rate the build quality as top-notch, save for the somewhat under-designed cable strain relief (located on the left can). The cable is about 3m log, it is coiled and it ends with a 1/8in jack. A screw-on 1/4in jack is also provided. The strain-relief of the cable at the can attachment point seems (to me) a little too small because the coiled cable is very heavy and with use (given sufficient time) I can see it failing and leading to cable/connectivity issues. Also (this is just a minor personal quibble) the silver velour pads may seem dirty depending on how the light hits them (but again, no big deal, especially since black-velour or leather pads for it are available on Amazon or elsewhere). On to sound quality: Computer/audio gear used during my listening tests: MacBook-Pro w/ Mac OS X 10.6.8 XMOS USB 2.0 Audio Reference Design Asynchronous DAC (44.1-192kHz/24bit), HiFiMeDIY Sabre USB DAC (32-96kHz/24bit), Matrix M-Stage Headphone Amp, FiiO E12-Mont Blanc Headphone Amp Beyerdynamic DT990-Pro Open Headphones (250 ohm, 96dB/mW) Audio-Technica ATH-A900 closed-back headphones (40 ohm, 101dB/mW), Superlux HD-681 semi-open headphones (32 ohm, 98dB/mW), and Sennheiser HD-598 open headphones (50 ohm, 100dB/mW). Playback software: Audacity, iTunes, VLC Source quality: standard CD 44.1kHz/16bit, and native HD 88.2-96kHz/24bit Audio cables: 3.5mm to RCA (3ft), and RCA-to-RCA (3ft), AUVIO and Monoprice brands The Sound (overall conclusion both DACs/HP-Amps): Good dynamics, detail and clarity, well staged and with good imaging. In terms of frequency response these headphones are tuned such as to emphasize/boost the low and high ends. Perhaps the best way to summarize the DT990-Pro sound by comparison with the other three headphones I have here would be this: The DT990-Pro nearly matches the Superlux HD681 in bass impact without sacrificing dynamics, it easily matches the Sennheiser HD598 in mid-range sparkle, staging, and imaging, and gives the Audio-Technica ATH-A900 a good run for the money in terms of highs extension. The closest of my other headphones in terms of overall SQ would be the Sennheiser HD598. However, despite the slightly more neutral presentation of the Sennheiser's, I find the DT990-Pro sound far more preferable. The DT990-Pro has a much better low end, and has smoother, more extended highs without that slight veil characteristic to Sennheiser headphones (clearly the Sennheiser HD-598 are decent cans but somehow I could never get too excited about their sound, hence my search for a different pair of open-back headphones). Also, the DT990-Pro manages to present the high end with what I'd call more "precision" than the ATH-A900 without sounding as grainy, and with just as much aplomb as the Superlux without sounding as (excessively) bright. Note: The DT990-Pro are both high impedance (250ohm) and relatively less efficient than the other cans I mentioned here (they only manage 96dB/mW) and thus amping is a must for anyone wishing to get the most out of them. For instance, my iPod Shuffle 1-st Gen (max output: 0.57Vrms) cannot drive them to any reasonable listening level (without severe clipping) and only manages a lifeless, distorted, garbled presentation, while the MacBook-Pro sound card (1.4Vrms) drives them to sufficiently loud levels but with pretty obvious distortions (for an overall harsh, fatiguing presentation.) Based on my experience with such sources I would not recommend these cans for use with portable devices without a proper amp. Also to note: the DT990-Pro do require at least 8-10hr of initial break-in to start sounding right (before that the sound is overly bassy, and somewhat unfocused/cloudy). As of this writing I have 30-35hrs on it and for sound quality I'd break things out like this: Bass Extension: 6/10 Bass Impact: 7/10 Bass Texture: 7/10 (solid) Mids Quality: 7.5/10 Highs Extension: 8.5/10 Highs Quality: 8/10 (vivid) Highs Texture: 7.5/10 (soft) Detail/Transparency: 8/10 (clear) Dynamics: 8.5/10 (natural) Soundstage: 8/10 Imaging: 7/10 Other: Isolation: 2/10 (open design) Comfort: 9/10 Design/Aesthetics: 9/10 (classic Beyerdynamic design) Build quality: 9/10 Portability: 5/10 (fairly large size) Improvement w/ Amplification: 8.5/10 (Note: Amping is recommended!) Value at MSRP: (9/10) [I gave it a 9/10 here only because, by comparison, the $30 Superlux HD681 is still a better bang for the buck!] To conclude, the Beyerdynamic DT990-Pro are near reference headphones which sacrifice some neutrality for the sake of a more natural sounding, or rather, a more fleshed-out acoustic presentation. As far as I'm concerned, it suffices to say that the DT990-Pro is the only headphone I have here that I can listen to (with any kind of music) without EQ and not feel that I might be missing something (and that, I think, says a lot). All in all, a remarkable offering from Beyerdynamic, highly recommended!

I am what you might call a "budget audiophile." I care deeply about sound quality, but I simply can't afford the kind of system I would want. Instead, I own a few pairs of high quality headphones, store my music in the Apple Lossless (ALAC) format, and play everything through a quality external DAC and headphone amp, the (unfortunately discontinued) Nuforce Icon HD. I was hoping that the DT-990-Pro would combine the best features of the Sennheiser HD 598 and the Audio-Technica ATH-M50, and that's more or less exactly what it does. Let me explain. About 50-60% of my music library is hard rock and heavy metal (everything from Black Sabbath, Deep Purple, and Guns N' Roses to Metallica and Pantera to extreme death and black metal like Suffocation, Nile, Immortal, etc.). Before I bought the DT-990-Pro, I owned two pairs of headphones, the HD 598 and the ATH-M50. The HD 598 dominates the M50 in almost every respect that audiophiles care about: significantly more clarity and detail, a wider and deeper soundstage, much better instrument separation, etc. Moreover, the 598 is known for its "laid back" presentation: the lower frequencies are recessed relative to the M50, and the higher frequencies sound "rounded out," so you don't get any booming bass or sharp (and possibly fatiguing) sibilance. Because of this, the HD 598 is ideal for recreational listening of jazz, classical, and lighter music that emphasizes clean vocals (I'm a big Fiona Apple fan, for example, and the HD 598 remains my go-to for that kind of music). However, with such a laid back presentation, it is suboptimal for hard rock and metal. With the 598, you don't get heavy and pronounced bass tones, the sharp "THWAP!" of the kick drum, and guitar solos that really soar above the music; in general it's just too smooth and wimpy for that kind of music. For this reason, I found myself reaching for the M50 whenever I wanted to listen to rock and metal, but I hated making the sacrifice in sound quality. Enter the DT-990-Pro. Some reviewers have complained about its relatively pronounced lows and highs, but in my opinion, that is precisely what makes it excellent for harder rock (as well as hip hop and electronic music). With the DT-990-Pro, you get a clarity and soundstage comparable to the HD 598--the DT-990-Pro is arguably slightly more accurate than the HD 598, especially at higher frequencies, but the HD 598 has more soundstage--combined with the "kick" of the M50. I no longer have to make any kind of tradeoff when I listen to Slayer and Testament. Now, these headphones are at the same time very versatile, and suit a wide variety of music. I am impressed by how good they sound no matter what I throw at them: Brahms, Dvorak, John Coltrane, Charles Mingus, Ornette Coleman, Hendrix, Pink Floyd, Depeche Mode, Aimee Mann, Radiohead, the Wu-Tang Clan. So do not get the impression that these are "specialty" headphones suitable only for rock and metal. Far from it. As other reviewers have already noted, the DT-990-Pro is very, very comfortable--indeed the most comfortable headphones I have ever worn. A word of advice: at 250 Ohms of impedance, it does require a headphone amp to be driven properly and produce sufficient volume. If you plan on listening directly through a laptop or portable music device, I recommend the 32 Ohm "Premium" model. Given its excellent sound and versatility, the DT-990-Pro may be the best headphone in its price range.

I’ve been using the DT 990 Pro headset for a while now, and overall it’s one of the best audio experiences I’ve had—especially for the price. Sound Quality: This is where it really shines. The audio is super clear with a wide soundstage, which makes a huge difference for gaming and music. You can hear footsteps and directional cues way better than with typical headsets. The bass is present but not overwhelming, and the highs are very crisp (sometimes a little too crisp depending on the track). Comfort: Extremely comfortable. The velour ear pads are soft and breathable, and I can wear them for hours without any discomfort. The clamping force is just right—not too tight, not too loose. Build Quality: Feels solid and durable. Definitely built to last. The cable is attached (not detachable), which might be a downside for some people, but it hasn’t been an issue for me. Things to Consider: • These are open-back, so sound leaks in and out. Not ideal if you’re in a noisy space or don’t want others hearing your audio. • They don’t have a built-in mic, so you’ll need a separate one for gaming or calls. • Depending on the version (like 250 ohm), you may need an amp to get the best performance. Final Thoughts: If you care about sound quality and comfort, these are absolutely worth it. Just make sure you understand the open-back design and setup requirements before buying. Verdict: Amazing for gaming, music, and long sessions—just not for noisy environments or plug-and-play simplicity.

I finally decided to take the plunge into a really nice set of headphones - my nicest set previously was a set of $60 Sennheiser HD 429's. While those were decent, they didn't come anywhere close to some of the high end cans that I had tried and I got tired of being disappointed every time I listened to music or watched a movie with them. After months of shopping around online and reading reviews I decided to visit a music store to try some out. After all my due diligence I had settled on the Audio-Technica ATH-M50S but I didn't buy them at the store since I knew I could get them online for cheaper. Well, when I went to buy them here on Amazon I read through a few reviews and saw Beyerdynamics mentioned over and over again, and after reading a lot about them I decided that I wanted to spend a few more bucks and try out the DT-990 Pro 250 Ohm. It was a bit of a risk since I hadn't tried them in person but knew I could return them if not happy with them. Well, they showed up today - in fact I'm listening to them right now - and let me just say that as soon as I finish this review I'm going to buy another pair for my wife. Bottom line: WOW! The sound that these headphones produce is the most open, deep, detailed, crystal clear sound that I have ever heard. I was a bit concerned about the 250ohm rating at first because I didn't know if my gear would be able to drive them without an amp, but both my PC and Oknyo receiver can power them with no problem. I do have to crank it to about 80% of max volume on my PC to get the sound level that I want, so I'll still probably invest in an amp to be able to drive them at a lower level for cleaner sound. I also want to be able to use them with my wife in the theater room after the kids have gone to bed and I'll need a multi-channel amp to do that. But holy cow these things have low hitting bass, the midrange is tight and crystal clear, and the highs are powerful but not overpowering. They are very well balanced. So far I've listened to some rap/hip-hop, metal, emo, classical, and even opera, and these things shine with any genre! I am so excited to watch a movie them. I really like the open back and I think that'll be nice when watching a movie with the wife so we can still talk to each other without having to completely remove the headphones. These are worth every penny if you're in the market for a nice high-end set of headphones. The only drawback is that you can clearly hear everything that you're listening to on the outside due to the open back, and I imagine they won't block outside noise very well, but I just plan to use them at home in a quiet environment like my office or theater room where it won't matter if they leak a little sound and there won't be any ambient noise to worry about. P.S. Forgot to talk about comfort, which is OFF THE CHARTS! They a have nice furry covers which are extremely comfortable, the clamping pressure isn't too tight, and I FINALLY found a set of cans that has openings big enough to fit my huge ears! With the M50S that I was going to buy my ears hurt after demoing them for about 20 minutes, and the clamping pressure was pretty tight but I read you can stretch them out to improve that. But I've been wearing these straight out of the box for nearly 2 hours now and just took them off and I don't even feel like I've been wearing anything. That is so much better than the normal 5-10 minutes of aching ears after taking off pretty much any other set of headphones that I have ever used. So if you have large ears or a big head these are perfect for you!

BeyerDynamic DT 990 PRO bought Aug 26 2014, 1 month ago, $175 US Sennheiser HD 560 ovation II bought March 23 1994, about 20 yrs ago, $350 CDN ($330 US). I wanted a replacement headphone for my HD 560 (ovation II), which has reached the end of its life cycle. I wanted one that would be cheaper and sound as good as the HD 560 once did. It must be comfortable for continuous hours of use. I'm 50 and I compose, mix and master my own tunes using a midi controller keyboard and VSTs. I decided on the DT 990 PRO. At $175 on Amazon US they were in my price range, but at double the price on Amazon Canada they were not, which is why it can pay to shop Amazon US. First, the claims. Sennheiser writes in its manual "Audiophile quality 'open-aire' stereo headphone considered by many to be among the finest in the world." For 1994, I agree. BeyerDynamic writes "The weight of the diaphram and moving coil of this headphone is approx. 20% compared to other current models. As a result, the DT 990 PRO offers similar pulse characteristics as electrostatic headphones." Hmm. My concern is they don't say if the reduced weight would shorten the diaphram's lifespan. My guess is yes, or why would they leave this out? Something to consider before buying. Next, the specs. Both are circumaural. HD 560: 14-35KHz 10 dB, 300 Ohms, 200 mW power, 94 dB, <0.2% THD, 2.5N headband pressure, 210g. DT 990 PRO: 5-35KHz, 250 Ohms, 100 mW power, 96 dB, <0.2% THD, 3.5N pressure, 270g (box says 250g). With my (unreliable?) fish scale, I weighed the HD 560 at 170g and DT 990 PRO at 190g. Half the mW power means the DT 990 PRO can't take as much abuse as the HD 560. Again, something to consider before buying. The comfort level. The DT 990 PRO makes the top of my head tender after hours of use. Unacceptable, so I unbuttoned and removed the headband wrapper and replaced it with a patch of felt. This makes the headphones feel/seem lighter, reduces pressure around the ears, and I can use them for hours without much discomfort. But it does appear to change the sound quality very slightly. Because of this I would have given it a lower 3 rating, if it weren't for the sound... The sound. Elite. I knew the HD 560 was lacking in bass, even when I bought them. The DT 990 PRO adds a lot of bass; almost too much, and throughout the frequency spectrum. This has the effect of increasing presence and bringing out subleties everywhere that are lost with the HD 560. Highs and mids are lowered, and bass goes down into the subs with clarity and power. However, the sound stage is much wider, making it harder to locate the pan positions of instruments. For example, with the HD 560's small sound stage, it's easy to say "the trumpet is 20 deg to left of center". With the DT 990 PRO it's not as easy. The DT 990 PRO's highs, mids and bass are exceptionally clear and nuanced, but my HD 560 has had 20 years of heavy use and abuse, invalidating a real sound comparison quality-wise. I can say this: play Lisa Kelly on my HD 560 and she sounds perfect, clear, effervescent, and blends nicely with the music. Play her on the DT 990 PRO and she's singing right in front of me, with a naturally slight tremolo in her sound. Almost creepy. I think that's due to the added bass power and wider sound stage. The negatives. I wear glasses and they squeak against the earpads. Adjusting my glasses forward a bit removes the squeak. For some reason, compared to the DT 990, the PRO bends the earcup extenders to fit inside the headband wrapper. Because the cups can rotate left/right, the extenders tend to catch and snap hard against the metal headband, making an awfully loud click in my ears when I put them on. Again, unacceptable for $175 headphones (now $200). To fix this, unbutton the headband wrapper and forcefully bend the extenders until they're straight, away from the metal headband and wrapper. BeyerDynamic says all parts are replaceable, yet the headphone cord doesn't detach from the earcup. This can be good, as my HD 560 frequently shorts at the earcup connectors. I hate the small, flimsy custom connectors on the HD 560. But it's also bad - I could unplug and replace the HD 560 cord (3 times!). I wonder how to replace the cord on the DT 990 PRO when it goes? A DIY task? I'm using a Pyle Pro PHA40 amp rated at 80 Ohms. An amp makes a difference, but I think the DT 990 PRO needs a good, matching rated amp to get the most out of it. Some reviewers have complained of ear fatigue after prolonged use. The manual does recommend a lower listening volume. As for lack of bass; this is false. There is more than enough bass, when amped. Despite the heavier weight, negatives, and my headband and extender fixes, I'm happy with my purchase, and it's a worthy successor in sound to my HD 560. But, I can only hope it will last 20 years, like my HD 560 ovation II did. (PS: my HD 560 were made in Ireland not Germany, DT 990 PRO are made in Germany. Two awesome countries!) YK
