The beyerdynamic DT 990 PRO (250 Ohm) is a world-renowned, open-back dynamic headphone engineered for professional audio engineers, music producers, mixing specialists, and broadcast content creators who demand pristine acoustic transparency and exact soundstage positioning. Operating on an open-back acoustic design that allows sound waves to vent naturally, the DT 990 PRO delivers a wide, three-dimensional soundstage with precise stereo imaging and outstanding impulse response. Its custom 250-ohm drivers produce a detailed high-frequency response and rich, articulate low-end reproduction across a 5 Hz to 35,000 Hz frequency range. Handcrafted in Germany with a spring steel headband, durable plastic ear enclosures, ultra-soft replaceable velour ear cushions, and a flexible 3-metre coiled connection cable, these reference headphones ensure ultimate fatigue-free comfort during long studio sessions.
Staff Take: The Expert Verdict
The single strongest selling point of the beyerdynamic DT 990 PRO is its iconic open-back spatial separation and detailed high-end resolution. The standout feature is its 250-ohm open transducer architecture, which eliminates internal cabinet reflections to give mixing engineers a accurate presentation of acoustic depth, reverb tails, and subtle stereo placement. We highly recommend these headphones for studio producers, mixing and mastering engineers, and critical listeners who work with dedicated audio interfaces or headphone amplifiers and need transparent monitoring comfort for hours on end.
Why Choose the beyerdynamic DT 990 PRO Headphones?

-
Unmatched long-session comfort: Soft, breathable velour earpads and a padded headband reduce heat and ear fatigue during extended studio mixing sessions.
-
Rugged German construction: Hand-assembled with a spring steel headband chassis designed to withstand the physical demands of daily studio work.
-
Single-sided coiled cable: Includes a heavy-duty 3-metre coiled cable that prevents tangling while providing plenty of reach around mixing consoles and rack gear.

Who are the beyerdynamic DT 990 PRO headphones best suited for?
The beyerdynamic DT 990 PRO (250 Ohm) is engineered primarily for music producers, recording engineers, mixing specialists, and mastering technicians who require an unbiased acoustic reference. Its open-back enclosure provides the spatial freedom needed to analyze delicate EQ changes, reverb decays, and stereo balance without boundary compression.
For secondary applications, these reference headphones are a popular choice for podcast creators, voiceover artists, video editors, and home audiophiles who listen through dedicated audio interfaces, headphone amplifiers, or high-end DACs. The comfortable velour padding and lightweight clamping force make them ideal for anyone working long hours in quiet listening environments.
beyerdynamic DT 990 PRO vs Closed-Back Studio Headphones — What's Changed?
The fundamental difference between the open-back DT 990 PRO and conventional closed-back studio headphones (such as the DT 770 PRO or Audio-Technica ATH-M50x) is the acoustic enclosure architecture. Closed-back headphones trap sound inside the earcups to isolate the listener and prevent bleed into live microphones, which can sometimes build up low-end boundary pressure. The open-back DT 990 PRO allows air and sound to pass freely through the rear grilles, resulting in a significantly wider, more natural stereo field that mimics high-end studio monitor speakers.
Secondary advantages center around spatial accuracy and acoustic airiness. While closed-back models excel at tracking vocals and instruments, the open-back DT 990 PRO offers superior high-frequency clarity and transient detail, making it the preferred choice for surgical EQ adjustments, panning decisions, and full-mix balancing where total acoustic isolation is not required.
How to Set Up the beyerdynamic DT 990 PRO
-
Unpack the headphones and connect the 3.5mm mini-jack plug directly to your audio source.
-
For professional audio interfaces, mixing consoles, or headphone amplifiers, screw the included 6.35mm (1/4") gold-plated adapter onto the mini-jack plug.
-
Adjust the flexible steel headband sliders on both sides to achieve an even, comfortable fit over your ears.
-
Position the velour earpads so they enclose your ears completely without pressing directly on the cartilage.
-
Plug into a high-output headphone amplifier or audio interface capable of driving 250-ohm loads for optimal volume headroom and dynamic range.
-
Begin playback with your audio source volume set low, gradually increasing to a safe reference monitoring level.

Frequently Asked Questions
Can I plug the 250-ohm DT 990 PRO directly into a smartphone or laptop?
While you can plug them into smartphones or laptops using a standard jack or dongle, 250-ohm headphones require more output voltage than typical consumer devices provide. For best volume levels, bass dynamics, and overall clarity, we recommend driving them with a dedicated audio interface, DAC, or headphone amplifier.
Do the DT 990 PRO headphones leak sound into the room?
Yes. Because these are open-back headphones, sound vents naturally out through the rear metal grilles. They are designed for quiet studio rooms, mixing environments, and home listening rather than loud public transport or live microphone recording booths where sound bleed might spill into sensitive mics.
What is the difference between the DT 990 PRO and the DT 770 PRO?
The DT 990 PRO is an open-back headphone designed for mixing, mastering, and spatial reference listening. The DT 770 PRO is a closed-back headphone designed for sound isolation during live recording tracking, monitoring in noisy environments, and punchy low-end isolation.
Are the velour earpads replaceable when they get worn or dirty?
Yes, absolutely. beyerdynamic manufactures official replacement velour earpads (EDT 990 V) that snap easily onto the earcup rims, ensuring your headphones stay clean, hygienic, and comfortable for years.
What is included in the box with the headphones?
The package includes the DT 990 PRO (250 Ohm) headphones with a fixed 3-metre coiled cable, a gold-plated 6.35mm (1/4") screw-on adapter, a drawstring drawstring protective storage bag, and the instruction manual.
