Beyerdynamic DT 990 PRO X
An open-back studio headphone for critical listening, with a 45mm dynamic driver and 48 ohm impedance.
Overview
The Beyerdynamic DT 990 PRO X is an open-back, circum-aural dynamic headphone made for professional monitoring and critical editing. It uses a 45mm dynamic driver and has a 48 ohm impedance, so it works with a wide range of audio interfaces and headphone amplifiers without needing excessive drive power. The look stays close to the original DT 990 Pro series. The open-back layout gives a natural, spacious soundstage, which suits detailed audio work. The headband has an integrated recess at the fontanelle area, which takes pressure off the sensitive spot at the top of the head during long sessions. The 3-meter cable detaches at a mini XLR connector, so replacing it is easy.
Design
Beyerdynamic stresses serviceability on the DT 990 PRO X. It says that with replaceable parts, it's built to last for years. The open-back design supports accurate sound by minimizing enclosure resonance, and the circum-aural earpads fully enclose the ears. The pressure-relief recess in the headband is a small feature that helps on long sessions. The cable detaches via mini XLR, a sturdy choice for professional gear. The overall construction is utilitarian and aimed at the studio.
Context
The DT 990 PRO X is positioned as an update to the original DT 990 Pro series. GadgetryTech called it "beyerdynamic's latest release" in June 2025, and Forbes confirmed it as shipping globally in July 2025. Its exact place in Beyerdynamic's lineup isn't specified, but the design and marketing suggest it continues the brand's open-back studio headphones. whathifi.com (September 2025) called it "the best wired over-ear headphones you'll find at that price," and pointed to its neutral, well-composed sound. No original price is documented.
