Sennheiser’s HD 400 PRO are a new pair of professional headphones for mixing, editing and mastering.
The HD 400 PRO studio reference headphones are specifically targeted towards 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. Plus, the unit includes both coiled and straight detachable cables, allowing the headphones to adapt to different use preferences.
“We are happy to introduce the first open studio headphones in Sennheiser’s PRO line,” commented 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 frequency response of 6 to 38,000 hertz, while the Sennheiser-developed 120-ohm transducers include a diaphragm made from a special polymer blend, which together with driver magnets, deliver well-defined bass. Distortion is below 0.05% (measured at 1 kHz, 90 dB SPL).
The headphone transducers sit at a slight angle, carefully recreating the optimum triangular listening position one would place themself in when listening to monitor loudspeakers in a recording studio.
