Our purpose is to review together all of the different musical instruments we come across and test so you can choose what suits your needs… There is a sub boost noticeable around the 30 Hz mark on the low frequencies of the Sennheiser HD 400S. This adds extra energy to every song that uses sub frequencies as a means for whipping up emotional impact. It achieves a perfect balance by boosting the lows without covering the low-mids in a shroud. The HD 400S exacts a secure clamping force around the head while remaining comfortable. Built into the underside of the headband is thin padding coated with soft rubber or silicone material to ensure the headphones stay in place. 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.

The audio cable is removable, but unfortunately the connector is not compatible with external cables. The cable also has a remote and measures 140cm. Build Quality: When unboxing the headphones I didn't think they were gonna fit as they looked small in both the ear cups and headband. But once I wore them, the headband adjusted nicely and the ear cups fit nice and snug (still comfortable), keep in mind my ears are pretty big lol so in my opinion it should fit most people. Unfortunately the headband is made of plastic but for price range I can't complain especially considering the audio quality.

Prices valid in stores (all including VAT) until close of business on 1st November 2023. (Some of these web prices are cheaper than in-store, so please mention that you've seen these offers online.) 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 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. The high frequencies of the Sennheiser HD400S have emphasis in various places across the lower treble, upper treble, and upper octave. However, it also has a cut around what sounds like 9 kHz. As a result, the highs have a unique shape that is able to give detail to high frequency instruments while avoiding sibilance. The Sennheiser HD 400s headphone features a sensitivity of 120 dB and an impedance of 18 Ω. With a total harmonic distortion of 0.5 %, this headphone delivers clear sound quality. The cable length of 1.4 meters makes it easy to use with various devices. Featuring a closed acoustic system, this headphone gives an immersive sound experience. The Y airplane plug and microphone input add to the convenience of usage for travelers and professionals alike. Though it weighs 217 grams, it is comfortable to wear for extended periods.

For example, when I was listening to the song Miles Runs the Voodoo Down by Miles Davis, the wide-panned electric guitars and keys contrasted well with the trumpet in the center. Additionally, the highs of the cymbals and trumpet contrasted wonderful in height from the body of the bass guitar and toms down below the head. The sense of depth wasn’t much to write home about, however came through in the song when the far off snare fills entered. These fills contrasted well with the intimacy of the trumpet. Overview
