The short version
The DT 900 PRO X is an open-back studio headphone with a 48-ohm STELLAR.45 driver, a detachable mini-XLR cable and velour pads, built in Germany according to the maker. Its low impedance lets it run from laptops and interfaces without a dedicated amp. RTINGS measured a well-balanced sound with a spacious soundstage, though low bass is thin as with most open designs, and it has no mic. It suits mixing and neutral listening at a desk rather than noisy spaces.
Pros
- 48-ohm impedance drives easily from laptops and interfaces
- Detachable mini-XLR cable with 3 m and 1.8 m options
- Well-balanced, spacious sound per RTINGS
- Velour pads and handmade build in Germany, per the maker
Cons
- Lacks low-bass rumble, typical of open-backs
- No microphone
- Vocals can be slightly veiled, per RTINGS
Best for
- Mixing and mastering at a desk
- Neutral listening without a dedicated amp

Common questions
Does the DT 900 PRO X need an amp?
Beyerdynamic designed its 48-ohm STELLAR.45 driver to work with interfaces, laptops, tablets and phones, so a dedicated amp is not required for typical listening levels.
Is the DT 900 PRO X open-back?
Yes. Beyerdynamic specifies an open design, and RTINGS describes a wide, open presentation with little isolation and audible leakage, so it suits quiet rooms rather than shared spaces.
What cable does it use?
Beyerdynamic ships a detachable cable with a 3-pin mini XLR at the headphone end and a 3.5 mm jack with a 6.35 mm adapter, in 3 m or 1.8 m lengths.
