Features
■ Sound that Meets the Needs of Professional Musicians and Engineers
With a wide frequency response range of 6 to 38,000 Hz, these headphones allow you to capture the full picture of sound accurately. The transducers developed by Sennheiser are equipped with diaphragms made from a special polymer blend. Combined with powerful driver magnets, they deliver exceptionally clear bass with fine detail. The HD400 PRO also accurately reproduces sounds outside the audible range, rendering delicate musical nuances and a clear low end.

■ Optimal Listening Position for Monitoring
The HD400 PRO’s transducers are slightly angled to recreate the optimal triangular listening position, similar to listening to monitor speakers. Additionally, the open-back housing of the HD400 PRO provides a natural sound spread, offering a soundstage with natural transparency and depth.

■ Comfortable Fit for Extended Use
The ear cups are precisely designed to fit around the ears with minimal pressure. The soft velour ear pads provide a pleasant touch, allowing you to focus on monitoring even during long sessions.
