Reference-quality headphones for project and professional mixing sessions

By reproducing analytical sound, the HD 400 PRO reference headphones are your everyday tools to get the job done.

Open back, open mix

Open earcups create a wide and transparent soundstage, simulating the optimal listening position of high-end recording studios. Artifacts of confined spaces are a thing of the past. These studio headphones don't construct, but rather deliver neutral transparency—the foundation for the best mixes.

The perfect synergy of comfort and precision

Let's face it, mixing sessions are never over quickly. The lightweight design of the HD 400 PRO allows you to stay focused on your project for hours. The articulating earcups, velour earpads, and adjustable headband offer adaptability and comfort to perfectly fit your head shape. Our proprietary 120-ohm transducers are precision-tuned to deliver every detail of your mix. The highly efficient driver magnet ensures clarity, while the damping system manages ventilation. This results in deeper bass while reducing distortion, which would otherwise compromise sound quality—a difference professional users will appreciate.
