รหัสสินค้า : SENNHEISER-HD400PRO

The Sennheiser HD-400 Pro is a pair of open-back, circumaural studio headphones that conceal highly sophisticated technology behind an unpretentious appearance. The black headphones impress with a very wide frequency range, from an ultra-low 6 Hz at the bass end of the spectrum to as high as 38 kHz in the treble range. The HD-400 Pro is intended to allow analytical sound judgements to be made. Accordingly, manufacturer Sennheiser describes its sound as natural, transparent, and precise. These headphones also work with Dear Reality's dearVR Mix software. A technology called Spatial Headphone Compensation (SHC) is used here and ensures a reliable assessment of audio mixes in different virtual listening environments so that a mix can be optimised for as many listening situations as possible. The scope of delivery includes two different interchangeable cables with 3.5 mm mini-jack connectors as well as a 6.35 mm jack adapter.

Powerful reference model

Sennheiser presents the HD-400 Pro headphones as a reference against which the quality of other headphones from the manufacturer should be measured. Its features include angled drivers that are supposed to provide the best possible stereo image. With all of the sound refinements that these dynamic headphones offer, the maximum sound pressure level they produce measures a hefty 110 dB. If the HD-400 Pro is to deliver such a high volume despite its 120-ohm impedance, it is best powered by a headphone amp that can deliver a decent output voltage. For this reason, a separate headphone amp is recommended for laptop users and users of smaller audio interfaces in order to fully exploit the qualities of this open-back, over-ear model.

For friends of wearing comfort and signal fidelity

The Sennheiser HD-400 Pro is a good choice for mix engineers who want to judge ultra-deep bass with their headphones. Mixers who greatly value differentiated highs will also get their money's worth here. And thanks to its low harmonic distortion, audio enthusiasts who expect a very clean signal with hardly any distortion will also find what they are looking for. Fans of high wearing comfort will get a suitable tool with the HD-400 Pro as well: With its replaceable velour ear pads, it lies comfortably on the skin and, with its low weight of only 240 g without the cable, little to no feeling of fatigue can be expected, even during long listening sessions. Those who want to work with their studio headphones in a completely relaxed manner and without pulling on the cable can use the HD-400 Pro's straight cable, which has a practical length of 1.50 metres, instead of the included three-metre coiled cable.

It’s all in the mix. When working at home or in the studio, you need your mix to sound as it does when your listeners hear it. The HD 400 PRO reference headphones are your everyday tool to get the job done. Its open-back design provides a natural and accurate listening experience for fine tuning your signature sound. The core of the HD 400 PRO is the 120-ohm transducer developed by Sennheiser engineers, featuring a specialized polymer blend in its diaphragm. The highly efficient driver magnet provides clarity while its damping system manages ventilation. This results in deeper bass while extenuating distortion that otherwise impacts sound quality — a difference our professional users will appreciate. This makes the HD 400 PRO a precise monitoring tool which reveals your mix in every detail. Velour earpads and a distinct lightweight design provide the comfort you need during long sessions. The robust housing endures everyday wear and tear regardless of your application, whether editing, mixing or mastering. A single-sided and coiled cable gives you the freedom to operate. For convenience, a straight cable is also included in the delivery. In addition, open ear cups and angled transducers allow for a wide and transparent soundstage, recreating the optimal listening position found in high-end recording studios. Artifacts of a confined space are a thing of the past. The HD 400 PRO is a truly reliable companion for those who put quality and precision above all else.
