Beyerdynamic DT 770 vs DT 990

The short version of DT 770 vs DT 990: the DT 770 is a closed-back headphone built for tracking and isolation, while the DT 990 is an open-back designed for mixing and critical listening in a quiet room. They share the same legendary Beyerdynamic comfort and a similar bright, detailed signature, but the closed-versus-open difference changes which one is right for you.

Quick answer: Buy the DT 770 if you need to record vocals or instruments without mic bleed, or if you work in a noisy space. Buy the DT 990 if your main job is mixing and you can work somewhere quiet. Many home studios eventually own both.

DT 770 vs DT 990: the core difference

Both headphones come from the same Beyerdynamic Pro lineage, use the same 45mm dynamic drivers, and feel almost identical on your head. The defining split is the earcup design:

• DT 770 PRO — closed-back. Sealed earcups block outside noise and stop sound leaking out. That makes them ideal for recording, where a click track or backing mix must not bleed into the microphone.
• DT 990 PRO — open-back. Perforated earcups let air and sound pass through. This gives a wider, more natural soundstage that flatters mixing decisions, but it leaks sound badly and offers almost no isolation.

If you only remember one thing: closed for recording, open for mixing. This is the same logic we cover in open-back vs closed-back headphones.

Sound signature

Both models carry the classic Beyerdynamic “bright” voicing, with a noticeable lift in the upper treble that brings out detail, sibilance and cymbals. Listeners sometimes call it crisp; others find it fatiguing over long sessions.

• DT 770: Punchier, more present low end thanks to the sealed cups. Bass feels fuller and more physical, which some producers like and some find slightly emphasised.
• DT 990: Airier and more spacious. The open design gives a larger sense of stereo width and a more “speaker-like” presentation, though the treble peak is, if anything, a touch more forward.

Neither is perfectly flat, so neither should be your only mixing reference. They are excellent detail tools, but check your final balance on monitors and consumer earbuds too. For the bigger picture, see studio monitors vs headphones for mixing and our guide to reference headphones.

Soundstage and imaging

This is where the open-versus-closed design has the biggest audible payoff. The open-back DT 990 presents a wider, deeper stereo image because sound is not trapped against your ear by a sealed cup. Instruments feel like they sit in space around you rather than directly inside your head, which makes it easier to judge panning, width and depth in a mix.

The closed DT 770 has a more intimate, “in your head” presentation. That is not a flaw — it is exactly what you want when tracking, because you are concentrating on a single performance rather than evaluating a stereo field. For critical mixing decisions about reverb tails, stereo width and front-to-back depth, though, the DT 990’s open stage genuinely helps. If imaging is a priority, that points toward the open model.

Isolation and sound leakage

These two move in opposite directions, and it matters more than people expect:

• DT 770 (closed): blocks a fair amount of outside noise and leaks very little. You can record next to a live microphone without the click track or backing mix bleeding into the capture. It is also better for working in a shared or noisy space.
• DT 990 (open): offers almost no isolation and leaks sound freely. Anyone near you will hear what you are listening to, and a nearby mic will pick it up. It is for quiet rooms only.

If you ever track vocals or acoustic instruments with the headphones on, this single point decides it for you — the DT 770 is the only sensible choice. The leakage from an open-back like the DT 990 is enough to ruin a quiet vocal take.

Impedance: which version to buy

Both headphones ship in multiple impedance versions, and this matters more than people expect. The common options are 32, 80 and 250 ohms.

• 32 ohm: Loud and easy to drive from a phone or laptop. Good if you have no dedicated headphone amp.
• 80 ohm: The popular all-rounder for the DT 770. Works well from most audio interfaces and is a sensible default for tracking.
• 250 ohm: Needs a proper headphone amp or a capable interface output to reach full volume, but rewards you with the tightest, most controlled sound.

Match the impedance to your gear. If you are plugging straight into an audio interface, check that its headphone output can drive 250-ohm cans before buying that version — otherwise stick with 80 or 32 ohm.

Comfort and build

Comfort is where both headphones shine and where they are essentially tied. You get soft velour earpads, a generously padded headband and a light clamp that stays comfortable for hours — a big reason these are studio staples. The build is mostly plastic with a fixed (non-detachable) cable, either coiled or straight depending on the model. Earpads and many internal parts are user-replaceable, so a well-cared-for pair lasts years.

One small comfort note: the open DT 990 lets more air move around your ears, so it can feel slightly less warm and sweaty over very long sessions than the sealed DT 770. The DT 770’s closed cups trap a little more heat, which is the trade-off you accept for isolation. Both are far more comfortable than most headphones at their level, so this is a minor distinction rather than a deciding factor.

Can one cover both jobs?

If your budget only allows a single pair, the DT 770 is the more flexible choice because it can do both jobs adequately — it tracks without leaking and you can still mix on it, accepting a smaller soundstage. The DT 990 cannot track, so it is a poor “only headphone” despite being the better pure mixing tool. This is the same versatility argument we make in studio monitors vs headphones for mixing: pick the tool that covers the most of your real workflow. Whichever you choose, remember headphones flatter and exaggerate, so confirm your mixes on monitors and a couple of consumer playback devices before you call them done.

Which should you choose?

Choose the DT 770 if you record vocals, guitars or podcasts and need isolation so the mic does not pick up your headphone bleed. It is the safer single-headphone purchase for a tracking-focused home studio. Pair it with the workflow in how to record vocals at home.

Choose the DT 990 if your main task is mixing, you work in a quiet room, and you want the widest, most open presentation Beyerdynamic offers at this level. Just remember it leaks sound, so it is useless for tracking near a live mic.

If budget allows, owning both covers tracking and mixing properly. If you must pick one, the closed DT 770 is the more versatile starting point. Browse more options in our studio monitors and headphones hub.

Frequently asked questions

Is the DT 770 or DT 990 better for mixing?

The open-back DT 990 generally gives a wider, more natural soundstage that many engineers prefer for mixing. The DT 770 is still usable for mixing but its sealed cups make the stereo image feel smaller.

Can I use the DT 990 for recording vocals?

Not ideally. Open-back headphones leak sound, so a vocal mic placed nearby will pick up your backing track. Use the closed-back DT 770 for tracking instead.

Which impedance version should I get?

For most home setups running off an audio interface, the 80-ohm version is the easiest match. Choose 250 ohm only if you have a dedicated headphone amp, and 32 ohm if you mainly use a phone or laptop.
