Product Information
Beyerdynamic's open-back STELLAR.45 driver anchors this limited black edition studio headphone, delivering a frequency response of 5–40,000 Hz with distortion measuring just 0.05% at 500 Hz and 0.04% at 1 kHz. The DT 900 PRO X is designed for mixing and mastering applications where spatial accuracy and low-distortion reproduction matter at every stage of the process. Its 48 ohm nominal impedance works across professional audio interfaces, laptops and mobile devices, with sensitivity reaching 114 dB SPL at 1 V. The open-back circumaural design supports a natural listening experience, reproducing subtle detail and conveying spatial information with clarity.
Two detachable cables come included—3 m and 1.8 m—each terminating in a locking 3-pin mini-XLR connector at the headphone end and a gold-plated 3.5 mm jack with 6.35 mm adapter at the source. The STELLAR.45 driver handles short-term maximum input power of 100 mW and continuous operation at 30 mW, maintaining low distortion even at high sound pressure levels. Black velour ear pads and a soft memory foam headband apply 5.3 N nominal pressure for extended sessions, with the entire assembly weighing 345 g without cable. Manufactured in Germany with replaceable components and long-term spare parts availability, the headphones are built for extended service life, and a soft carry bag is included.
