The HD 400S features a one-button smart remote conveniently located on the cable, which allows you to control music and take calls with ease, and the sturdy folding design makes these headphones durable and compact enough to be taken anywhere. Sennheiser dynamic drivers deliver a well-extended sound response with dynamic bass.

The HD 400S offers great high frequency extension, bringing crispy goodness to percussion when listening to pop. At the same time, the highs steer clear of uncomfortable brightness. Testing out some violin solos in this range, there was a decent amount of transparency mixed in with a touch of smoothness. In the highest registers, there was minimal piercing or sibilance, so these cans work well for long listening sessions. SoundstageSennheiser's lineup typically focuses on quality audio reproduction. Many of their headphones are geared towards neutral sound compared to all-purpose headsets. 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. 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 The soundstage of the Sennheiser HD400S had a nice feeling of contrast in the height and width domains. It had a strong phantom center, which contrasted well with instruments panned out wide. Additionally, the height felt tall and deep with the sub energy in my chest complimenting the difference in the brighter, airer parts of the high frequencies. The sense of depth was skewed a bit due to the high mid boost, but came through depending on how it the mix used soundstage.

It’s almost annoying how predictably reliable Sennheiser’s headphones are. In this price range, the brand offers nothing flashy. Just skillful, well-balanced sound. Now, Sennheiser has introduced two new affordable HD models, which are successors to the HD 4.20. What can you expect in terms of sound signature and performance? Let’s take a look in this Sennheiser HD 400S Review. IN the BOX The middle frequencies of the Sennheiser HD400S have a little bit of a low mid boost around what sounds like 300 Hz. As a result, bass guitars, pianos, electric guitars, and strings have a nice base. However, I wouldn’t describe this feeling as a feeling of body. On the contrary, a cut around 1 kHz followed by a boost in the high mids gives these headphones a little bit of a smiley face curve in the midrange. As a result, it doesn’t feel cloudy at all, but it skews the levels of midrange instruments in the mix. Because of the high mid boost, vocals tend to sit a bit louder in the mix.Like all of Sennheiser’s stuff, the build quality on the 400S looks pretty solid. And because the cable is detachable, it can easily be replaced if it eventually fails on you. Add to that a 2 year warranty, and you should be safe for a while.

It becomes clear right from the first notes that the Sennheiser HD 400 Pro are detailed in the highs, but not annoyingly brilliant. The tonal harshness sometimes heard with other headphones is absent here. As is typical for open headphones, the Sennheiser have no annoying compression in the bass range. Nevertheless, they are by no means thin in the lower frequencies. Even the deepest sub-basses are easily perceptible. This is where the ultra-wide frequency range of their reproduction comes into its own. If you're an audiophile, you know this manufacturer as one of the key players in high-end reference headphones. They mainly produce these under one name: One of the main considerations Sennheiser had for the HD 400S was its context of use. These headphones have a very low impedance, making them perfect for mobile devices that might not have the power to drive more resistant headphones. The driver is still of Sennheiser’s own design and can balance clarity with power. The detachable cable features a control unit with a built-in mic of excellent quality, especially for calls.

The low frequencies of the Sennheiser HD400S has a sub boost around what sounds like 30 Hz. As a result, it gives lots of wonderful energy to songs that utilize sub frequencies as methods of creating emotional impact. It does a great job of making the lows sound big without getting in the way or clouding up the low-mids.
