HERE'S THE LINK TO THE HEADPHONE STAND IN MY PHOTOS: [Edit - One month after purchase: Buy these. You won't regret it.]I purchased the 32 ohm version of these headphones for $170 as I bought them Open Box (Perfect Condition) from a different seller on Amazon. I attached images for this review because it is very truly in perfect condition and I'm very happy with my purchase. The box was very clearly used and beat up, but the headphones themselves were very nice and the only signs of previous use were fingerprints on the metal parts of them which were easily removed.Sound Quality:I'm no expert on audio but I do prefer to have the best audio I can for a decent price, and these just about fit the bill. They are open-back headphones and the soundstage is amazing. These are my first ever pair of open-back headphones and I am blown away by how awesome they sound. The bass is perfect but not overpowering. The mids are fine, they aren't nearly as recessed as some people claim. The highs can be a bit tinny and painful but I think that's just from being so used to bassy headphones before these. After a day or two of use I've gotten adjusted to the sound of the highs and the clarity is really nice. If it bothers you too much you can always download an EQ program to soften them a bit.[Edit - One month after purchase: The highs have softened by a ton and are really pleasant. I'm not sure if it's due to break-in or just me getting used to them, but they are astounding sounding headphones. Best purchase I made this year, without a doubt. Great for gaming, watching movies/shows, and listening to music. Fantastic!]Build:Absolutely phenomenal! These are extremely light at 290 grams and the metal parts are sturdy. My only complaint with the build is that the adjustable parts of the headband are a bit wobbly and tend to "snap" into place randomly if you didn't adjust it perfectly. It's a minor issue that really doesn't take away from the experience, it's just a bit of a scare every once in a while if you forget they do that sometimes. Definitely not worried about them breaking at all, I think it's just a compromise from having more adjustability in the ear cups. The grills are metal and tend to attract fingerprints, as well as the tabs on the headband. The supports connecting it to the headband are also metal but have a more matte finish that doesn't seem to attract prints at all. The other parts are plastic with the headband being covered in an interesting layer of leather/foam material.[Edit - One month after purchase: No problems with build at all, still. The cable seems to coil up on its own which is a bit of a pain, but really the least of my concerns.]Comfort:Pretty darn good. I'm used to having gaming headsets that are designed for hours and hours of use, and at this rate, I don't think any earcups will be as comfortable as the ones on Razer headphones. I don't know how they make those so insanely soft and plush, but they will forever be my favorite. The DT990 ear pads have an extremely soft velour covering over an angled plush material that contours your head better than typical earcups. They aren't as plush as my old Razer headsets, but they don't really need to be because these headphones are so light. The ear cups are absolutely massive and I can't imagine anyone having trouble fitting their ears in these, even people with bigger heads. I have a medium/small head and small ears and these adjust to even smaller sizes than I need, but I'm not sure that people with absolutely massive heads will get quite the size they need. I added a photo of them fully extended, if that may help. The headband is soft but still firm, but they are so light that doesn't really matter. The clamping force is okay, they don't feel like they'll fall off my head easily but I do wish it was just a *tiny* bit looser. It's not unbearable at all though, and it seems like I just need to get used to it. The open back nature also adds to comfort, somehow. It doesn't feel like the sound is coming from anywhere, it's just there near your ears, instead of traditional closed-back headphones which feel like the sound is actually being projected from a source into your ears. For these, the sound just... happens. It's really lovely. Very easy to forget you're even wearing headphones.[Edit - One month after purchase: The clamping is no longer an issue. I can wear these all day with no headaches. Either got used to them or they loosened up a bit with use. Either way, they're wonderful. I tried replacing the ear cups with leather ones, but they made the sound signature less unique and the openness of the headphones was compromised more than I'd like. After going back to the originals, I'd have them no other way. Ich habe im Lauf der Zeit zahlreiche Kopfhörer über 500 Euro gekauft und getestet und fragte mich irgendwann, wie sich eigentlich Kopfhörer in den unteren Preisklassen dagegen ausnehmen. Manche sind ja der Meinung, dass man heute nicht mehr als 200-400 Euro ausgeben muss, um guten Klang zu bekommen. Das kann ich bis zu einem gewissen Grad bestätigen.Bei Lautsprechern sagt man: Zwischen 50 und 500 Euro liegen Welten, zwischen 500 und 5.000 Euro Nuancen, und zwischen 5.000 und 50.000 Euro ein fester Glaube. Das gilt ähnlich auch für Kopfhörer, nur dass ich die Obergrenze, wo ich keine wirklichen Unterschiede mehr höre, bei 1000 Euro ansetzen würde. Ab einem Grado RS2e für 549 habe ich offen gesagt schon Probleme, noch wirkliche Unterschiede nach oben zu hören, so dass ich behaupte, dass man für weit weniger auch schon ordentlichen Klang bekommen kann. Vielleicht nicht den satten, vollmundigen Spitzenklang beispielsweise eines Audeze LCD-2 für weit jenseits der 700 Euro, aber einen frischen, Spaß machenden Klang kriegt man durchaus schon für weit weniger.Wofür dieser Beyerdynamic hier (die 32-Ohm-Variante) ein gutes Beispiel ist. In der Klasse unter 500 Euro wird auch eine Menge Enttäuschendes geboten (ich habe gerade einen Hifiman Sundara und einen Sivga SV007 zurückgeschickt, die optisch schick gemacht sind, aber mir für offene Kopfhörer viel zu dumpf, zu eng und zu wenig spritzig klingen). Der DT990 hingegen ist bis jetzt in diesem kleineren Preissegment meine persönliche Referenz. (Heute wird ja vieles als Referenz und Professional verkauft, darauf darf man nichts geben. Das ist das „Bio“ unter den Kopfhörern. Am Ende weiß niemand so wirklich, warum es draufsteht.) Der DT990 klingt so, wie ich das von einem Kopfhörer generell erwarte: lebendig, frisch, fröhlich, luftig, und mit einer hörbaren Bühne, also nicht den Klang direkt ans Ohr geklatscht. Das kann eben nicht jeder Kopfhörer, auch wenn er offen ist.Ich habe inzwischen ein Qualitätskriterium ausgemacht, das mir abseits aller Messkurven und Laborwerte sehr schnell sagt, ob ein Kopfhörer für meinen Geschmack taugt oder nicht: Ich muss mich auf das nächste Musikstück freuen. Tue ich das, behalte ich den Kopfhörer, tue ich das nicht, geht er zurück. Da können die Testzeitungen schreiben, was sie wollen. Den Beyerdynamic DT990 behalte ich.The best general purpose headphones you will find under £250. I have owned the 'Pro' version of these in 250Ohm as well and can say that these 'Premium' versions have a nicer and more sturdy finish/build as well as a straight, but still fixed cable. Besides that, they sound identical.Excellent for music listening, especially those who like energetic or bass heavy music. Top end clarity is up there, along with the typical Beyer U/V shape mids, bass extension is fantastic. Great headphones for across the board music tastes, but powerful music such as Rock / Metal / Electronic especially.Gamers will be blown away! Chuck your cheapo 'not famous for audio products in the slightest' gaming brand name headset out the window and buy these. Clarity and power like you have never heard.At 250Ohms they should really be driven by an amp. I can recommend Creative's Soundblaster X G5 or even the G1 if using them with a PC.I can say that if you are looking at these as your first set of good HiFi headphones then buy them, right now. You will not be dissapointed, these are easily the best, if not at least top 3 of most well balanced general use cans sub £250.The only reason to buy these over the cheaper Pro versions is that these have a straight cable and different finish. Apart from that they sound the same.I've never been into Audiophilic headphones, or got what the buzz was about getting expensive headphones.But these DT 990's really make me appreciate what it's all about, I can now hear instruments in some of my music I wasn't even aware of, it's almost like I'm listening to some songs for the first time again, but this time, they're are being heard the way they were meant to be heard.The base on these is clean, not too overpowering, but just enough to give you that oomph. The vocals and strings on these also sound pretty amazing, I have a feeling I won't be touching my old headphones ever again. I'm using the Creative G5 AMP/DAC, though not the best out there for these cans, they are adequate for now, but I'd say if you've got the cash and want the best experience, I would recommend the Schiit Modi and Magni DAC and AMP. They're American made, and they are top quality for their price. Just make sure you pick the UK plug before you order them.Playing games on these is also pretty incredible, the directional audio is on point. I've played racing games, FPS shooter (BF4) and these headphones are so much better than those "gaming" headphones, and without the fake 7.1 virtual surround feature, these headphones are best experienced in stereo.EDIT: I've had these for a few months now, and like a few others, I've begun to notice my left cups have a little rattling to them, and the right cups crackle sometimes. None of my other headphones exhibit this, so it has to be exclusive to these.I'm a bit disappointed to be honest, as the DT 990 Editions are the best headphones I've used otherwise.Great hi-fi headphones that double up as amazing gaming headphones too. After coming from a hyper-x cloud revolver s headset I can immediately notice the difference in better sound resolution and soundstage in music and games.I did plenty of research into other headphones and these suit a multi-purpose need. The dt 880 are slightly more musically focussed with more accuracy and semi-open design. I love the fully open dt 990’s for gaming. Just bear in mind you will hear outside sounds if you are somewhere noisy. As for talking into a microphone I find it nice to hear yourself clearly with these.As for the 250ohm pro vs this 600 ohm premium. From what I’ve read the 250 has piercing high frequencies where its more refined on the 600 ohm version along with other things and to me they sound great BUT I’ve not had the chance to physically compare any other hi-fi headphones.I am using a dedicated amp + dac with these. It may be overkill but I think it enables them to produce the best sound, especially as they are 600ohms with 97.56 dB/V SPL or 95.43 dB/mW sensitivity.You can use online calculators to see how much power an amp needs for these headphones. At 110db volume it needs 29mw or 4.17 VRMS. So I chose the JDS labs atom that provides 125mw or 8.68 VRMS at 600ohms.Another alternative set-up would be to use the Schiit magni amp + modi dac for about the same price but with way more power output compared to the one I chose. Apparently these sound very good, I just went with JDS because in a few audio tests on graphs it was a little better.So this is an out of the box review of the 990 edition, so first 24 hours of ownership.I am a bit of a headphone nerd so can tell pretty quickly if I’m going to like a pair of headphones. I currently own AKG 702 & 7xx, senn HD6xx and Philips X2HR headphones so I am comparing the 990’s to those directly.I bought the “edition” version as I wanted a straight cable and the few other tweaks they’ve made to make them more “home friendly”.Build and design: so they look cool, better in person and feel well built (much better than AKGs for example). I would’ve liked the shells and grills to be metal but this would increase cost and weight so not necessary and purely aesthetic.Comfort: these are very comfortable. When you first put them on they don’t feel like they are going to be as comfortable as people make out but very quickly you forget you’re wearing them. I would rate them right up there on comfort out of the box. Most people rave about 650/6xx being comfortable, rubbish, those things hurt unless you’ve got a peanut sized head or you stretch out the headband which is easy to do. These need no “breaking in” in the comfort dept.Sound (most important bit): these are right up there with the best at under 500 dollars/pounds. They seem to tick all the boxes and combine all the best bits of the other headphones. They have plenty of bass but not too much, clear highs and have an airy feel to them or “wide soundstage” for all the audiophile nerds out there.Negatives: I have got the 250 ohm variant and they are a beast to power. I have the 300 ohm 6xx and the 990’s are harder to power than those. I have a zen DAC currently which powers them ok but I’ve had to crank it to over 2 O clock on the DAC to get a good volume level (I do listen to metal so quite loud). The zen isn’t the most powerful so your mileage may vary but a headphone amp is a must for these. Go for the lower resistance headphones if you don’t want to buy or do not have a headphone amp.I love these headphones and they are definitely going to be keepers. My 702’s have already been packed away!
