Beyerdynamic DT 900 PRO X Studiohodetelefoner

Open-Back Studio Headphones for Critical Listening and Mixing

The Beyerdynamic DT 900 PRO X is a circumaural, open-back studio headphone built for mixing engineers and mastering professionals who demand a transparent window into their audio. At its core is the new STELLAR.45 driver, developed in Heilbronn, Germany, which delivers a broad 5 Hz to 40 kHz frequency range and operates at a 48-ohm impedance. You can use it at full studio levels from laptops, interfaces, or even phones without a dedicated amp.

What Sets This Model Apart

Featuring the STELLAR.45 transducer, which blends a neodymium ring magnet with copper-clad high-tech wire and a three-layer diaphragm with an integrated damping layer. This precise build keeps the voice coil perfectly centered during intense sessions, resulting in clean transients at higher volumes. For added precision, the Beyerdynamic HEADPHONE LAB software reads each unit’s serial number and applies a personalized calibration curve.
