Open-back studio headphones with 250 ohm impedance, 5 Hz to 35 kHz response and replaceable velour pads for critical mixing and mastering
Series DT 990 Pro
Model 250 Ohm
The Beyerdynamic DT 990 PRO 250 Ohm is an open-back circumaural headphone built for critical mixing, mastering and editing. Its 250 ohm impedance suits professional studio equipment and dedicated headphone amplifiers. The 5Hz-35KHz frequency response delivers transparent, spacious sound with precise bass and powerful treble presence.
Handcrafted in Germany with robust materials, the headphone weighs 0.55 lb and uses a single-sided coiled cable that stretches from 8.0 to 10.0 feet. A 3.5 mm mini-jack plug and 6.35 mm adapter are included for direct connection to interfaces and consoles. Replaceable velour ear pads and a spring steel headband maintain comfort and secure fit during long sessions.
Moving from closed-back or low-impedance headphones reveals far greater spatial imaging and detail retrieval for critical evaluation. The jump is worth it when you need to hear subtle artifacts, positioning cues and tonal depth that lesser designs conceal. Buyers who require isolation for tracking or portable use will not be served by this open-back design.

Other versions of this model
The 250 ohm impedance requires more voltage than typical portable devices provide, so volume will be lower than with low-impedance headphones; a dedicated headphone amplifier or audio interface is recommended for full output.
The circumaural ear cups fully enclose the ears with soft velour pads, and the spring steel headband flexes to fit a wide range of head sizes without pressure points.
The single-sided coiled cable is permanently attached; plug the 3.5 mm mini-jack into portable gear or screw on the 6.35 mm adapter for professional audio interfaces and studio equipment.
