Product information

Description

The Sennheiser HD 400S are wired supra-aural (around-ear) headphones designed for everyday use. They feature a comfortable headband, closed-back earcups that reduce background noise, and a detachable single-sided cable with an integrated one-button remote and microphone. The foldable, lightweight construction makes them easy to carry and store while Sennheiser dynamic drivers provide clear treble and strong, well-extended bass for an accurate listening experience.

Advantages

Renowned Sennheiser sound quality delivers a balanced audio signature with dynamic bass and clear highs. The integrated microphone and one-button remote on the cable let you control music playback and handle calls without removing the headphones. Closed-back around-ear design limits external noise for more focused listening, and the lightweight, foldable frame enables compact storage and portability.

Suitable for

Everyday music listening at home or on the go
Hands-free phone calls and remote control of playback
Commuting and travel where compact, foldable headphones are preferred

How to use

Connect the detachable RCS 400 cable to the headphones and plug the 3.5 mm angled jack into your device. Use the one-button remote to play/pause music or to answer and end calls; the in-line microphone picks up your voice for hands-free conversations. Fold the headphones along the hinges for compact storage or transport.

Usage recommendations

For best audio performance, use with devices that provide a standard 3.5 mm output. Keep the detachable cable dry and avoid excessive bending near the connector to prolong cable life. Store the headphones folded in a protective case or pouch when not in use.

Specifications

Ear coupling: Ear coupling describes the way in which headphones or earphones stay attached to, or inside, the ear. There are three common types of ear coupling: circumaural, supra-aural and intra-aural. Circumaural headphones enclose your ears with large pads that suppress external noise. Supra-aural headphones are typically more lightweight and sit on top of the ears with small pads. Intra-aural headphones come in two basic designs and neither style sits on the head itself. The first are ear buds, which sit just outside of the ear canal, on top of your ear lobes. The second type is actually inserted directly into the ear canal and offers some external noise suppression.: Supraaural
Connectivity technology: The technology that enables connectivity of the device, e.g. wired or wireless.: Wired
Recommended usage: What the product should be used for, and how it should be used (e.g. ambient temperature).: Calls/Music
Product type: The sub-category of the product.: Headphones
Product colour: The colour e.g. red, blue, green, black, white.: Black
Wearing style: The way in which the device is worn.: Head-band

Total Harmonic Distortion (THD): Total harmonic distortion is a measure of non-linear harmonic distortion and is given in %. Non-linear harmonic distortions are signals which were not present in the original before the signal was converted by the headphones. These unwanted signals are caused by the diaphragm, whose movements do not precisely move in time with the electric signals that cause it to move. Unfortunately, this is a feature of all electroacoustic transducers. Although it cannot be completely eliminated, suitable steps can be taken to minimise it. However, the user is not interested in why this distortion takes place but in how great the level of distortion must be for it to become perceptible. According to the findings of several research projects, a total harmonic distortion of 1% in the frequency range of 100 to 2000 Hz is imperceptible. Below 100 Hz, the perceptibility threshold lies at 10%.: 0.5 %

Impedance: The effective resistance of an electric circuit or component to alternating current, arising from the combined effects of ohmic resistance and reactance.: 18 Ω
