beyerdynamic DT 900 PRO X – 48 Ohm Open-Back Studio Headphones
The beyerdynamic DT 900 PRO X brings STELLAR.45 drivers, open-back acoustics and a detachable cable to a recording or listening desk. It is built for buyers who want a studio headphone that can move between compatible playback devices without committing to a high-impedance design.
Its 48-ohm impedance, replaceable wear parts and two included cable lengths make it a versatile tool. Use it in a quiet space where open-back sound leakage is acceptable, particularly when a live microphone is nearby.
Explore the Features

FEATURE 01
STELLAR.45 Driver
The 45mm dynamic driver is the core of the PRO X design. Its neodymium magnet and copper-clad high-tech wire voice coil support detailed reproduction without requiring a 250-ohm headphone output.

FEATURE 02
Open-Back Listening
An open construction supports spacious playback for music, editing and mixing. Listen in a quiet room so subtle changes are not masked by ambient noise.
FEATURE 03
48-Ohm Versatility
The moderate impedance makes it a practical option across many interfaces and portable sources. Actual loudness still depends on the source and recording level, so check the device you plan to use.
FEATURE 04
Two Detachable Cable Lengths
The supplied 1.8m and 3m cables let you choose a shorter desk route or more reach. The locking mini-XLR connector also separates ordinary cable replacement from the headphone itself.

FEATURE 05
Velour Earpads for Long Sessions
Soft over-ear velour pads create a breathable fit. Replace worn pads with the correct type to maintain the intended spacing around the driver.
FEATURE 06
Padded Headband with Pressure Relief
The headband padding and its pressure-relief recess help distribute contact on the top of the head. Adjust the fit before evaluating the sound over a longer session.
FEATURE 07
Replaceable Components
Serviceable pads, headband padding and cable support everyday maintenance. This matters for a headphone that will be used repeatedly rather than stored between occasional sessions.
FEATURE 08
Wired Simplicity, German Build
There is no battery to charge or radio connection to manage. The German-made construction keeps playback straightforward: connect a suitable stereo headphone output and set the volume.
Choose Playback or Recording at Your Desk
For music playback, compare the FiiO K7 and FiiO K11 by their inputs and single-ended headphone output. If the same desk also records microphones, the Scarlett 2i2 adds recording inputs. Use the supplied stereo cable with the appropriate single-ended output.
Frequently Asked Questions
Is DT 900 PRO X closed-back?
No. It is open-back and allows sound to pass in and out. DT 700 PRO X is the closed-back model in this family.
What is its impedance?
The DT 900 PRO X has a nominal impedance of 48Ω.
Are the cables detachable?
Yes. It uses a locking mini-XLR connection and includes 1.8m and 3m cables.
Does it work for gaming?
It can reproduce game audio through a suitable headphone output. It has no built-in microphone, so voice chat requires a separate mic.
Can it plug into 3.5mm and 6.35mm outputs?
Yes. The included stereo connections support 3.5mm and 6.35mm use. These are single-ended connections.
Is it the same as DT 990 PRO?
No. DT 900 PRO X uses STELLAR.45 drivers, 48Ω impedance and detachable cables. The classic DT 990 PRO has different impedance versions and a fixed cable.
