Explanation: In contrast to the full review, the QUICK VIEW only provides a brief tonal and functional overview. Either I haven't been able to spend enough time with the headphones, where the rating has to be taken with a grain of salt, or I don't consider it particularly worthwhile in terms of sound. I will mark which of the two variants applies with "Time", or "Average". The weighting of sound and handling is 2:1.

Quick View reason: Average Intro

The H400S is a headphone for mobile use, which can be used on a cell phone (18 Ohm, 120 dB) without any problems. It has good isolation, but the sound is too inconsistent and rarely works musically.

Handling Although the earpads seem too small for over-ears, they are very ergonomic and manage to be very comfortable for hours with a mixture of lay-on (in front of the ear) and ear wrap (behind the ear). In addition, they have a robust design with enough twist room for the ear cups and adequate padding, although the headband is somewhat uncomfortable.

The audio cable is removable, but unfortunately the connector is not compatible with external cables. The cable also has a remote and measures 140cm.


The bass is somewhat isolated from the rest of the signature and is really good in itself. Powerful with emphasis in the subrange, without exaggerating it. For driving beats or hip-hop a fun affair and quite detailed. But the mids are the deal breaker on the H400s. These are very unbalanced and especially voices are sometimes hard to bear as they can get very shrill. In general the H400S is too bright and tonally inconsistent. The trebles also don't have a big extension and sometimes sound a bit tinny.

You can't speak of naturalness or authenticity with the HD400S and it definitely can't be described as an all-rounder. Stage and imaging are average here.

Outro The HD400S is a headphone that has a good functionality, but the sound is very unharmonious and artificial. Some music styles work quite okay with the HD400S and the bass is very well done, even if it seems to be split off from the mids and highs, but almost 70 € (RRP) can surely be better invested if you have a demand for sound.
