At a time when virtually all audio companies are offering headphones for use at home or in the studio, mostly without distinctive features, Sennheiser correctly decided to look at its own portfolio full of original designs and excellent drivers. Seemingly inspired by the highly awarded Sennheiser HD 560S reference headphones, the German specialist launched the new HD 400 PRO dynamic, open studio professional headphones for mixing, editing, and mastering.
The HD 400 PRO reference-grade studio headphones are an ideal companion for creators seeking natural and precise sound reproduction to accurately assess their audio mixes. To ease long sessions, the HD 400 PRO features a comfortable and lightweight open-back design fitted with soft velour ear pads. The unit includes both coiled and straight detachable cables, allowing the headphones to adapt to different user preferences.
“We are happy to introduce the first open studio headphones in Sennheiser’s PRO line,” comments Gunnar Dirks, Product Manager, Professional Audio. “When editing and mixing, you need detail and honesty, and this is what the HD 400 PRO will give you. Thanks to their linear, high-resolution reproduction, these headphones are a reliable reference to create outstanding audio mixes.”
The HD 400 PRO features a wide frequency response to give music producers the full account of their mix and to better accommodate current frequency response target calibration solutions that are becoming common in studio environments. The Sennheiser-developed 120-ohm transducers include a diaphragm made from a special polymer blend, which together with powerful driver magnets yields deeper, yet totally clear and well-defined bass. Distortion is below 0.05% (measured at 1 kHz, 90 dB SPL).
The HD 400 PRO accurately reproduces audio beyond the audible frequency range, offering “access to nuanced harmonics and ambiance in music, while at the same time revealing a bold, articulate low-end,” the company states.
The headphone transducers of the HD 400 PRO sit at a slight angle, carefully recreating the optimum triangular listening position that users would adopt when listening to monitor loudspeakers in a recording studio. In addition, the open-back design of the HD 400 PRO ensures a natural propagation of sound, unimpeded by the acoustic structures required in closed-back designs. Both aspects create a wide and spacious soundstage, neutral and transparent, which enables audio producers to work confidently.
And probably more important for many users, the HD 400 PRO headphones feature high comfort that prolongs creativity. A carefully engineered ultra-light frame positions the earcups in place, gently hugging the ears with minimal pressure. Soft velour earpads allow users to focus on projects for hours on end, while the open, circumaural design offers sufficient ventilation for ears to keep their cool, even during long mixing sessions.
The HD 400 PRO headphones are available now and retail at USD $249 (MSRP). The headphones come with a 3-meter coiled cable and a 1.8-meter straight cable, both fitted with a 3.5mm (1/8”) jack plug for portable sources. A 1/4″ adapter is included, ensuring that the HD 400 PRO connects to professional mixing desks or audio interfaces.
