Sennheiser HD 400 PRO Studio Headphones

Sennheiser has introduced its new HD 400 PRO studio reference headphones, intended for use in mixing, editing and mastering applications.

Built around a lightweight, open-back design fitted with soft velour ear pads, they are the first open studio headphones in Sennheiser’s PRO line, and offer a wide frequency response of 6 to 38,000 Hz.

The Sennheiser-developed 120-ohm transducers include a diaphragm made from a proprietary polymer blend; working with the headphones’ driver magnets, according to Sennheiser, the diaphragm is expected to provide deeper bass. Distortion is below 0.05% (measured at 1 kHz, 90 dB SPL), and the headphones are said to accurately reproduces audio beyond the audible frequency range.

The headphone transducers sit at a slight angle, aiming to emulate the triangular listening position used when listening to monitor loudspeakers in a studio. This, along with the open-back design of the headphones is intended to provide a neutral soundstage.

The headphones are built around an ultra-light frame; the earcups feature soft velour earpads and the open, circumaural design offers ventilation for ears during long mixing sessions. The headphones come with a 3-meter coiled cable and a 1.8-meter straight cable, both fitted with a 3.5 mm (1/8″) jack plug for portable sources. A 6.3 mm (1/4″) adapter is included, ensuring that the HD 400 PRO connects to a typical mixing desk or audio interface.

The HD 400 PRO is available now and retails at US $249 (MSRP).
