Almost perfect
125000 18.02.2018
I bought these, the dt-880 (600ohm) and the hd-650.
And I'll quickly write why I picked the 990's over the others.

The dt-880's were amazing, so comfortable, perfect in my opinion.
While the 990's are really similar, they are tighter on the ears, and I don't like that at all, but they are still quite comfortable.
And the hd-650? They clamp like crazy, I couldn't wear these for over 10 minutes, really uncomfortable.

Now this category is objective af, you have been warned.
I used the LP-phone-amp-g103 to drive all of these headphones so there shouldn't be any issues with the amp.
With that out of the way, lets start with the headphones that really disappointed me.
The 880's had a really lackluster low end, you could say non existing, and with basically no bass it was just a clear no for me and I didn't bother any further with them.
The hd-650 sounded like the 990's if someone put an equalizer on them that turned down every frequency past 3khz down 3-6db.
They sounded muddy in my opinion, especially compared to the dt-990's.
With that being said, I love the by some considered sharp highs of the dt-990's, everything sounds crystal clear, not "muddy" or "washed out". I listen to a lot of vocals so that's a must for me. But as I said, it ain't for everybody since some might say the highs are over saturated, and they are, but it sounds nice. It's something I'm looking for in headphones, are you looking for that? If not steer away from these headphones. Cons: they might be too sharp for some and too tiring if used in long sessions. Other cons are the fact that you can really hear if a song is mixed/mastered like shit, you can hear everything. I'm not gonna say sh*t like :"you suddenly hear instruments that you previously didn't hear" if you suddenly heard an instrument that you didn't hear before on decent headphones that's on you. But you definitely hear if someone didn't bother cleaning up the samples he used in his song, and you might need different headphones or speakers to enioy songs that are badly mixed.

price/performance: 10/10, I mean ¤140 for these is a steal, you don't get better audio quality for that price, but you probably gonna need a headphone amp as for almost all 250+ ohm headphones.


Great value open-back with well-balanced sound
Enriconism 24.07.2021
I'm happy with this purchase! I'm not exactly an audiophile, but play and listen to a lot of music and do a small amount mixing / production. My previous headphones were good but exaggerated the bass. I also wanted open-back cups for comfort in long sessions.

These sound clear from low to high volume, and have a very neutral EQ response - I immediately could tell why I had trouble mixing music to sound good both on my old headphones and speakers. With these, the response is much more level and "true".

I am very happy using these when playing a digital piano, again with responsive sound and wide feeling stereo. A bonus using open-back is that when I sing while playing piano with headphones (or just talking in general) it now feels really natural, without that "underwater" voice resonance sensation of closed headphones.

The comfort is very good overall. Cups are large and well padded and easily fit over my ears - no pressure points or discomfort after hours of continuous use, even while wearing glasses. The open back allows to hear the environment around me and prevents hot or "pressured" environment for the ears.

Build quality is good overall, but there are a few edges on the metal and plastic that could be smoother. The metal frame is quite stiff, so it takes two hands to adjust the height of each cup (at least they stay in place!). It's also not possible to adjust the clamping strength of the frame - for me luckily it is a good fit.

I like the long cable with provided jack adapter. It is flexible and light, and can easily span several meters. The coil returns to shape well and does not pull or weigh heavily.

As you would expect, these headphones are not sound-isolating, so you shouldn't use these in a noisy environment. However, the sound does not leak out too strongly. Listening at a reasonable volume, it should not disturb someone sitting next to you. When recording vocals, I have had no issue with "monitor feedback" leaking from the headphones to the mic.

They have held up well over a few months of use now, still seems as new.

- Great value
- Clean sound with clear frequency response
- Nice size and padding of cups
- Long and light cable
- 6.3 and 3.5mm support

- Stiff frame with somewhat limited movement or adjustment range
- Cable is fixed to the headphones (understandable at this price point but a detachable / replaceable cable attachment would always be a plus for me)


Shocking good sound quality for the price point!

Rather exciting piece of headphones!
Although they have advertised 250 Ohms impedance you average smartphone can drive them pretty well to painfully strong sound pressure level. The caveat however is that if you pair them with a simple amplifier you will unleash the beast <1KHz. I was pleasantly surprised when I first tried them on my phone, then thrilled on my audio interface Komplete 2, finally the HA4 "KOMPLETED" the circle of audio pleasure. I compared them directly to Custom One Pros, Marshall Major and K-701 all four driven from the same source - Komplete 2 + HA4. I equalised the volume to the best of my perception and the DT 990s wiped the the floor with the competition.

Sound: 5 stars - NO DOUBT ABOUT! (Metal, rock, classical music listener here)
Comfort: 5 stars - Pretty fluffy ear cups. I wear glasses and my deal breaker is that the headphones do not press my ears too hard against the frame of the glasses. I do however fear that during summer the ear cups will be a bit too warm.
Quality: 4 stars - Overall pretty solid BQ. I do not like the way that metal brackets on both sides are attached to the head band (Mechatronics engineer's inner voice says - FLIMSAAY!). Luckily ALL parts can be ordered as spares from beyer when they break. I am also not of fan of the fixed cable... that should've been a detachable 3.5mm jack like many other less expensive headphones. The cable itself is a bit of overkill sized gauge telephone coil. It is massively thick and heavy and absolutely not portable. It's not a big problem for stationary setups but please take in into account for portable intentions - they are not.


Parfait pour l'edit et l'aide au mix
Bert Werbrouck 21.06.2021
Les plus:
- Très bonne qualité de fabrication, comme d'habitude avec les casques Beyer.
- Très confortable pour les longues sessions, ce qui est très important
- Pas trop difficile à "driver". Même s'il est en 250 ohms, c'est ok sur ma scarlett 18i8 ainsi que sur la sortie casque de mon portable récent mais moyenne gamme. Pratique aussi pour les longues formations en distanciel (le côté ouvert du casque rend le tout hyper confortable)
- Peu flatteur, détaillé et précis, ce qui est clairement ce que j'attendais. Je l'utilise le plus pour des edit de pistes et il est vraiment pratique pour vérifier qu'il n'y ait pas de pops, clics, que les fades soient naturels lorsqu'on cleane les pistes, etc. Il doit aussi avoir des avantages au niveau du mix (pour certaines applications) et même de la prise, si vous utilisez des dynamiques peu sensibles sur une voix par exemple (ce n'est pas recommandé mais la repisse serait très faible et ça peut mettre à l'aise les chanteurs.euses qui n'ont pas l'habitude de chanter avec un casque fermé).

Les moins:
- ... son côté peu flatteur et précis. C'est pas un casque "plaisir". On retrouve la signature typique des casques beyer, avec peu être un côté un peu plus "bright": extension dans les basses généreuse, médiums très légèrement creusés, aigus hyper détaillés. Perso, j'adore.
- Le cable attaché... mais tout est remplaçable (en ce compris le cable) donc ce n'est pas trop un souci
- Le soundstage est toujours aussi impressionnant que sur mes DT770 mais pour un casque ouvert je m'attendais à un changement un peu plus net. C'est peut-être une question d'habitude... ou juste que les DT770 sont très impressionnants de ce point de vue pour des casques fermés.

En résumé: c'est fiable, précis, solide et pas trop cher donc si vous voulez un casque ouvert, foncez
