The Sennheiser HD 400 PRO open-back studio headphones deliver neutral, precise reference sound for mixing and mastering. Lightweight with velour pads, 120Ω dynamic drivers, angled transducers for wide soundstage and dual cables (straight + coiled) ensure comfort and accuracy during long sessions.

The HD 400 PRO’s open-back design and angled drivers create a natural stereo image and precise spatial imaging for critical mixing and mastering.
The 120 Ω dynamic drivers cover 6 Hz to 38 kHz. Low distortion and a 110 dB SPL rating help reveal the nuances of a recording, even during extended sessions.


Velour ear pads, a lightweight design at 240 g, and two detachable cables—a 3-meter coiled cable and a 1.8-meter straight cable—support work in the studio and with mobile setups.
