DT 990 PRO 250 Ohm Open Dynamic Studio Headphones

Just received these this afternoon. I already own Amirons, DT 880s and DT 770s and Grado SR80s. I’m not a fan of Sennheiser, so anyone who is familiar with both Beyerdynamic and Sennheiser headphones will appreciate that this is a subjective review by someone who likes Beyerdynamic’s house sound. This review is my assessment of them purely for home use. There are obviously loads of reviews of the 990s on the internet, and although very popular they obviously divide opinion. I shan’t make out that these are for everybody, but I’ll add my three pennies worth here which might cut through the superlative laden ayes and the damning nays and help some people to make up their minds on whether or not to buy a pair (I dithered for far too long). When I was in my early twenties I might have found the Beyerdynamic sound too bright and analytical, but back then I could hear frequencies up to 20khz; not so now, at 63 my hearing tops out just under 14khz, so maybe this accounts for my later-in-life infatuation with the Beyerdynamic sound. Though I like most forms of music, the bulk of my collection veers towards acoustic music - classical, jazz etc - there’s also a fair bit of dub reggae, rock, EDM and so on (so, it’s basically Prince Far-I to Schubert, Aphex Twin to CSNY, Thelonious Monk to Joni Mitchell, Public Enermy to Spirit, Poppy Ackroyd to Bob Dylan - catholic, essentially). I’ve only had a few hours to make comparisons (Bill Withers, Thelonious Monk, Radio 3, Bill Charlap, Heart of the Congos, Lana Del Rey), but I think this has given me adequate opportunity to make a pretty accurate judgement of the characteristics and comparative merits of the 990s. I’ve been listening to them mainly through a Little Dot Mk 2 with a combination of Novosibirsk and Mullard 8100 valves (sourcing from a Cyrus Cd and Cyrus 8 DAC amplifier). I’m delighted with the 990s. They are neither shriekingly sibilant nor either lacking or over-endowed with bass. Compared to the other headphones that I own I would say that the 990s are nearest in sound to the 880s. Indeed, I think that they are very near sound-wise. The 880s are marginally more polished, but the difference (to my ears at least) is subtle rather than dramatic. I would suggest that the 990s are very good, cheaper alternatives to the 880s. The 880s clamp the head noticeably more lightly than the 990s, but the 990s are more secure on the head. Sound leakage is similar in both, so neither are good for listening to next to your sleeping partner (who hates going off to music and especially hates jazz) in bed unless you want a poke in the ribs. For this I have the 770s, which have a somewhat “fuller” or “fatter” sound than the other two. Leakage on the 770s is minimal at low to modest volumes. The Amirons (Homes) are, to my mind, decidedly more “musical” or “liquid” sounding headphones, very enjoyable for extended listening and very revealing, in comparison with those I would describe the 990s and 880s as rather “analytical” sounding and the 770s are somewhat “dryer” (I hope describing their sound as both “dryer” and “fatter” doesn’t sound like a contradiction in terms but I can’t immediately think of a better words to describe the sound). However, they’re all good and all have what you might call a “house sound” (i.e. a Beyerdynamic sound), although the Amirons depart furthest from this sound (which isn’t really very far at all) while the others might all be considered even more typical. The Amirons have a fuller, certainly pleasant and, I would say, slightly coloured bass by comparison, the bass on the 880s and 990s is leaner and, as far as I am qualified to judge, seemingly more accurate. Some people say that they both lack bass, but I don’t think this it true, it is most certainly there when it’s there! It may be that those who think they lack bass are listening to these headphones without suitable amplification. As goes the 770s, I’d say that their bass - in terms of weight - lies in the middle here, it is perfectly good but it is neither as accurate as on the 880s and 990s nor as pleasurable as on the Amirons. Sound stage is best, and very similar, on the 990s, 880s and Amirons. I wouldn’t say that there is any vastly significant difference here between these three headphones. The 770s, being closed-back, are noticeably more “closed-in” in terms of soundstage but, in terms of closed-back headphones per se they’re actually really rather good in this area; I’ve certainly not encountered a closed-back pair that are better (or indeed any other closed-back pair that I can actually bear - I personally much prefer open-back designs, for me the 770s are exceptions in this department). The 1770s may well be better, but I’m not about to fork out several hundred pounds more for those when I use closed-back headphones mostly for listening in bed via the headphone output of a Roberts radio. As regards comparison with the Grado SR 80s, the 990s and 880s are decidedly superior sounding, with the Grados sounding rather rough and uncouth by comparison (though this isn’t helped by the Grados comfort levels which are simply not in the same league - half an hour with Grado SR80 ear pads is sheer torture; consequently I’ve replaced them with Sennheiser HD414 ear pads which improbably (as, apart from being yellow, they don’t seem materially that different from the Grado pads) improve matters a fair bit and don’t noticeably change the SR80s sound). The Grados do sound more bassy, but this is definitely a matter of quantity rather than quality. Build quality on the Grado SR80s is also markedly inferior to that of the Beyerdynamics. I would retire the Grados at this point, but their 32 Ohm impedance makes them useful. They’re good fun, but they’re not good for extended listening sessions. The 990s and 880s with their 250 Ohm impedance definitely need amplification. I use a couple of Little Dot Mk 2s. The Amirons have the same impedance but are significantly more sensitive. For unamplified use I find the 770s a better match with their 80 Ohm impedance (they certainly work well with most Roberts radios of recent years, Roberts seem to have pretty good headphone circuits on their radios). Summing up, I think that the 990s are fantastic value for money (the Amiron Homes, which I love, are perhaps a clear case of diminishing returns by comparison). If you’re thinking of buying a pair of Beyerdynamics, want open-backed headphones, fancy the 880s from all you’ve read, but feel that the 880s are a stretch for you financially, then I think you’d be missing very little with the 990s in terms of sound). Originally, I had thought of purchasing Beyerdynamic’s new DT900 X headphones, but - reading the reviews, and knowing how much I already liked the sound of the 880s and 770s - I thought I’d save myself some money and get something that might not sound so hugely different for half the price and, beyond that, I actually prefer the look of the 990s. I don’t rule out considering the new series in future, but for now I don’t feel I’m missing out on anything that would be game-changing, although I admit I’m curious. As I have found repeatedly, however wild the superlatives I encounter in the reviews the actual differences between the last and the latest model of a particular piece of hifi is more often than not a matter of nuance. Whatever way you cut it, comparing the 990s with the highly regarded and (to me) very similar sounding 880s and the more refined, more relaxed, but four or five times more expensive Amiron Homes, they are still very good sounding headphones and first class value for money - assuming, like me, you like the Beyerdynamic sound. If you’re a Sennheiser fan you’d probably be barking up the wrong tree (but you know that already) and, if you’re a Beats fan, then presumably you’re already stone deaf. And then again, as goes highly regarded budget headphones, I reckon they knock the Grado SR80s into a cocked hat. But not everyone would agree with me. Anyway, I hope all that helps. Update, 28/1/22. I’ve now spent some more time listening to the 990s on a Little Dot Mk 2 with a combination of Novosibirsk and Radio Technique valves (sourcing from a Naim CD5 via a Rega Elex R). The Radio Technique valves are very similar to the Mullard 8100s I used at the top of this piece. Continued close listening has only confirmed my sense of how good these headphones are. On further consideration, with this set up, I’d say their sound signature lies between that of the 880s and the Amirons. I’d say they sound slightly “weightier” than the 880s and that the Amirons are a bit more so, but the differences here are more subtle than seismic. On careful comparison, after a few hours of listening, my overwhelming sense at this point is that, if you like open-backed headphones, like the Beyerdynamic sound and have a hankering for a pair of Amirons but either can’t afford them or can’t justify the expense, then you really wouldn’t be missing very much at all by just settling for a pair of 990s. By comparison they are a real bargain and, I think, in absolute terms they are quite simply one of the best bargains there is on the headphone market. One further point, on comfort, although the 990s have more clamping force on the head, I actually find them more comfortable than the Amirons as they fit my head better. Finally, as anyone who has read this far has already probably figured out, it has cost me quite a lot to reach my conclusions here. I think I have a reasonable sense of humour, but if you’re an audiophile sceptic then I guess I can understand why you may feel you’re getting the last laugh! I’m glad I own the Amirons, they are very nice headphones, but if I could only have one pair I must admit that I’d very happily settle for the 990s. Postscript, 31/1/22. On further reflection, it’s very good having several headphones all sharing a general character that I like, but each a little different from the others. Different music works best on certain headphones (for instance, listening to Beatrice Rana’s performance of the Goldberg Variations this morning I much prefer the rendition of her piano’s sound through the Amirons to that of the 770s (the piano sounding decidedly more lifelike through the Amirons), whereas with Thelonious Monk’s It’s Monk’s Time the difference is less obvious and, if anything, I’d say I actually prefer the 770s with their greater attack. But, different music is not all: different recordings, different source equipment, different mood of the listener ... however, it’s very quick and easy to change between modestly priced headphones during a listening session in order to optimise your listening experience (something you can’t readily do with expensive speakers, amplifiers, cartridges and so on).

Fantastic product, no issues. Sound quality is great, just the right amount of sound penetration from outside but also not too much. Headset is a bit uncomfy when first use but with wear becomes incredibly comfortable. Plenty of wire length and very easy to untangle. Sturdy metal frame and design feels premium and strong.

3rd of 4th pair of these headphones I've had, outstanding for the price. Soundstage is excellent, bass is accurate and punchy, the high end takes some getting to used to but is near perfect. I could go on but these are simply delightful to listen to from an audio standpoint. Comfort wise they are the most comfortable headphones I have ever used, the ear cushions can be easily replaced if they get worn/dirty also. The only thing I will warn potential buyers about is the that the headband can snap over time, but to be honest when you use these daily for 10-12 hours I think its reasonable that they begin to wear after 3-4 years.

I have owned a pair of Sennheiser HD-580 Precision headphones (they based on the original HD600, and use the same driver) for many years now, but having gone over from using Hi Fi separates, to computer based audio equipment, I have been longing for a slightly more powerful sound, something that has a little more impact and sparkle than my old HD-580s, which are a lovely sounding headphone. I was initially sceptical about these Beyerdynamic DT990 Pros, simply because of the low price, and the deep confusion that surrounds all the various different ohm ratings Beyerdynamic use across many of their ranges. It seems that the sound actually varies depending on which impedance rating you end up purchasing, as to if you will get too much treble, or too much bass, or deeply recessed mids. After spending much time reading many reviews and forums regarding the DT990 Pro, versus the DT770/880 Pro range, I settled on the 990 Pro 250 Ohm version, as it's hard to justify double the cost for the 32 OHM versions of these. After opening up the box, I was instantly reminded that the cable is of the coiled variety. This kind of reminds me of those big boxy headphones you could get in the 70's! However after actually using the headphones, the coiled cable is actually better for me than having nearly 3 meters of cable hanging on the floor in front of my computer, where I sit when listening to music. So, just to set the scene, the 990's are connected to my computer via an Objective2 headphone amp, with built-in ODAC, connected to the computer using USB. I use J.River Media Player v19, and have it set to directly connect to the ODAC at 24Bit & 44KHz Sample rate. I started out by having my trusty Sennheisers connected first, and listened to some music, just to give myself a reference point for the 990's. Then I quickly replaced the Senns with the 990s, and wow!!! To my surprise, the 990's actually sounded slightly louder, and had much better bass, and much more detailed upper mids and treble. The overall midrange was about the same as the Senns, so I was instantly in love with the 990's! They have a wider soundstage, as well as better positioning compared to the Senns, which kind of sound a little lifeless in direct comparison to the 990's. My o2 amp really got the Senns working as well as my old Hi Fi seperates used to, but they lacked impact in the bass, and always were a little dull sounding in the top ranges (the infamous Sennheiser veil at play!). These 990 Pro's just give me all that is best about the Sennheiser 580's, but improve on the bass and detail, making them a really good and balanced sounding headphone. I can only think that those who claim these 990 Pros have a recessed midrange are using either badly matching equipment, or just bad equipment in the first place. I find the bass on the 990's are very deep, rich and fast. They really brings out sub-bass nicely, but not in an artificial or bloated way, it really has to be heard to be understood properly! The upper bass notes are natural, tight and punchy, certainly not of the one note variety, which the Senns can tend to be with some music. The treble is definitely more present than my Sennheisers, but I would not call these artificially bright by any means, but it is fair to say that these headphones require a good quality headphone amp, something with a neutral sound. If your equipment is on the bright side, then these headphones may be a little revealing of that. I find the DT990 Pros to be very comfortable, and have a relatively low clamping force, slightly lower than all my Sennheiser headphones that I've ever owned, so I'm not sure why some people claim these headphones can be a little tight on the head, I almost wish they clamped a tiny bit harder! The velour earpads are really comfy, and very similar in feel to the Sennheisers. (sorry to keep comparing these phones to Sennheisers, but the senns are a gold standard, and twice the price of these, so I think it's fair to compare. I have not had a chance to try these with my iPhone 5, or my iPad 3 yet, but I think these headphones probably will not be efficient enough, and will lack volume, but when I get the time to try them out, I will update this review. The bottom line is that at £120, they are an absolute steal. I think you would have to spend more than 3 times this money to actually get something with a better sound. Maybe the Audeze LCD2 would be a nice, noticeable step up, but anything else would not really have the value for money factor that you get with the 990 Pros!

Beyerdynemic DT 990 pro is professional users for sound engineer, value for money, perfect balanced sound.

Le uso ormai da più di un anno in modo praticamente ininterrotto e non ho mai avuto un solo ripensamento. Comodità top, le indossi per ore senza affaticarti, e il sound è davvero impressionante: dettagli nitidi, scena ampia, bassi presenti ma mai esagerati. Si sente che sono fatte in Germania, materiali solidi e zero scricchiolii. Per mixaggio o anche solo per ascoltare musica come si deve, per me restano una scelta sicura.

Amazing I love watching movies with these or even playing games like valorant, dying light, uncharted, god of war even watching vox machina it picks up everything top notch!!

expensive but worth it, best for music composers and also for gamers. but sure you need must a DAC/AMP for this . Otherwise sound too much low cause low power, you must need a amp for this

Muy buen producto, busqué antes reviews entre distintas web junto a comparativas técnicas (consumos y curva de sonido), con lo que terminé entre los DT990 y los akg702 (otros que me parecieron interesantes fueron los DT770 y akg701). Antes que nada, lo que diré no es para un uso profesional, por lo que mi percepción no será igual según el uso que se le quiera dar, yo los utilizo estrictamente para escuchar música y para jugar al ordenador con amigos por Discord. También soy músico y me considero algo elitista en cuando a cómo suenan mis aparatos. Recomiendo para los que tengan Android (necesario tenerlo ROOT), que se instalen Viper4Android desde xda-developers, este permite mejorar el sonido enormemente parametrizando con muchas opciones. COMPARACIONES Pude compararlos con unos Pionner de tipo semi abierto del rango de 40€, donde estos últimos se notan más graves y con mayor carencia de agudos. Con los DT990 sí pude notar que los agudos son más perceptibles, o que no están "mezclados", pudiendo distinguir mejor ciertos sonidos de otros. También pasaron por mis manos unos cascos abiertos de 800€ (no me acuerdo de la marca) que se escuchaban mejor, pero siendo prácticos, esa diferencia era casi inapreciable (principalmente en en agudos y algo en medios) y no merece a no ser que tengas un muy buen equipo de música de alta fidelidad de los caros junto a archivos también de alta calidad, FLAC o streaming de TIDAL (Spotify no es "tan" bueno en esos entornos). Comparando con unos in-ear (xiaomi pro hd en mi caso) todo depende la calidad de estos (he comprado 4 o 5 in-ear con anterioridad y parecían basura comparado a estos últimos). Tras editar el sonido con Viper4Android, los in-ear no tienen nada que envidiarle a los DT990. Hablando del sonido puro, sin modificarlo, los in-ear dan muchos más graves, con un sonido en general bueno y sin carencias, lo que podría distinguir a los DT990 es la claridad con que se escuchan los agudos principalmente o el poder distinguir un poco mejor cada una de las fuentes de sonido (pero muy poco). AMPLIFICADOR DE AURICULARES (no necesarios) Todo dependerá del dispositivo al que los quieras conectar, yo los he probado con un pc y dos móviles sin necesidad de un amplificador extra. La placa de mi pc está preparada para entregar audio a auriculares de hasta 600ohmios, al 60% se oye muy bien. En cuanto a los móviles (xiaomi MI3 y MI8) sin tener activo el mod Viper4Android, al 80-90% se escucharía normal, por lo que si eres de los que te quieres quedar sordo o simplemente hay mucho ruido en el exterior es posible que el 100% se quede algo corto. Con el mod Viper4Android se puede amplificar el sonido casi al doble si no se quiere saturar (permite más pero ya no sonaría bien), con mis ajustes escucho música al 50% de volumen. CONSTRUCCIÓN DE LOS DT990 El cable en espiral no "tira" tanto, si está conectado a algo sólido o pesado se podrá estirar bien sin problemas. El acabado de las piezas de la diadema parecen robustas, aunque hace un "clak" cada vez que me los pongo. Lo que no me gusta nada es el pequeño cable externo entre la diadema y cada uno de los cascos, aunque este tipo de construcción evita pinzamientos del cable y así que no se degrade, es posible que se pueda enganchar con algo si no se tiene cuidado. También, son muy cómodos, no aprietan demasiado y cierran bien alrededor de la oreja (considero tener orejas de un tamaño medio). Otro punto a favor es que no aprietan las monturas de las gafas como me pasaba con otros cascos, evitando el malestar tras muchas horas de uso. CONCLUSIONES Todo dependerá del uso, pero estoy casi seguro de que el consumidor medio no notará casi la diferencia entre estos cascos y otros del rango de los 70-80€ en cuanto a sonido. Es muy importante el tipo de cascos (cerrados, semi abiertos y abiertos), estos al ser abiertos son los más cómodos y con mejor sonido, aunque se colará algo de sonido al exterior y los graves no están tan presentes (se puede arreglar con un ecualizador si se quiere). Estoy contento con el producto, quería tener unos cascos "buenos" dentro de un rango de precios que me dure para siempre.
