Other product features:
A professional tool with neutral sound reproduction
Lightweight design for all-day use
Single-sided coiled cable for greater freedom of use. A smooth cable is also included for wider use.
Angled transducers designed for low distortion at high sound pressure levels provide a spacious and accurate sound image.
Reference-class headphones for project work and professional mixing
The HD 400 PRO's frequency range is designed to sound unbiased across the spectrum, which is particularly evident at the low end. The angled transducer design allows for a unique stereo imaging that reproduces the spatial sound of the mix.
In other words: What goes in, comes out. Its reproduction of analytical audio makes the HD 400 PRO reference headphones the perfect tool for everyday work.
Open design, open mix
The open earcups provide a wide and transparent sound image, creating the optimal listening position known from high-end recording studios. Artifacts from confined spaces are a thing of the past. These studio headphones do not interpret, but provide neutral transparency - the basis for the best mixes.
Perfect synergy of comfort and precision
Mixing sessions are usually very time-consuming. Thanks to the lightweight design of the HD 400 PRO, you can comfortably concentrate on your project for hours. Movable ear cups, velour ear pads and an adjustable headband provide adaptability and comfort, perfectly hugging the shape of your head.
Our in-house designed 120-ohm transducers are tuned for accuracy and reproduce every detail of your mix. The high-efficiency driver magnet provides clarity, while its damping system regulates airflow. This ensures deeper bass while mitigating distortion that otherwise compromises sound quality - a difference that professional users appreciate.

The HD 400 PRO features a detachable coiled cable.
A plain cable is also included for a wider range of uses. With a screw-on adapter, you can connect your mixer, audio interface, or any other audio device with a 6.3 mm or 3.5 mm output.
