When you work at home or in the studio, you need your mix to sound its very best. The HD 400 PRO open-back studio headphones deliver a natural, accurate listening experience to refine your sound signature. The lightweight design and velour ear pads give you the comfort you need during long sessions. In addition, the open earcups and angled transducers create a wide, transparent soundstage, making the HD 400 PRO a reliable companion for those who put quality and accuracy first.

Reference-quality headphones for professional projects and mixing sessions:
The frequency range of the HD 400 PRO has been developed to be honest at every level, especially at the low end of the spectrum. The angled transducer design creates a unique stereo image, reproducing the spatial sound of your mix.
In other words, what goes in is what comes out. Reproducing analytical audio, the HD 400 PRO reference headphones are your everyday tool for getting the job done.

Open back, open mix:
The open earcups create a wide, transparent soundstage, recreating the optimum listening position found in high-end recording studios. The artefacts of a confined space are a thing of the past. These studio headphones do not interpret, but instead deliver neutral transparency – the foundation of the best mixes.

The perfect synergy of comfort and precision:
Let’s face it, mixing sessions are never quick. The lightweight design of the HD 400 PRO lets you focus on your project for hours. Swivelling earcups, velour ear pads and an adjustable headband provide adaptability and comfort that fit the shape of your head perfectly.
Our in-house developed 120 ohm transducers are tuned for precision to deliver every detail of your mix. The highly efficient driving magnet delivers clarity, while its damping system manages ventilation. The result is deeper bass, while reducing distortion that would otherwise affect sound quality – a difference professional users will appreciate.

More tools for more options:
The HD 400 PRO has a detachable coiled cable. For convenience, a straight cable is also included in the box. With a screw-on adapter, you can connect to your mixing desk, audio interface or any audio device with a 1/4 inch (6.3 mm) or 1/8 inch (3.5 mm) output.
