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.
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. Soundstage For example, when I was listening to the song Didn’t Cha Know by Erykah Badu, the high-hat had emphasis, but felt less chunky than usual. It was emphasized more toward the upper treble and octave. Additionally, the hand drum had a slightly different shape than usual, but maintained a good balance in the mix. Lastly, Erykah’s vocal had nice detail and had good audible air during the “oo”s and “hey”s. Soundstage With an inline mic and remote, the Sennheiser HD400S headphones are the perfect on-ear headphone match for your smartphone or tablet. 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.For example, when I was listening to the song Daydreaming by Middle Brother, the stringiness of the acoustic guitar felt emphasized over its body. Additionally, while the electric guitar had a sense of midrange, it leaned a bit toward the high mids. It was able to maintain its sense of harmonic complexity, but had a particular sense of clarity. For other genres, this may have felt somewhat thin, but for this genre it worked quite well. Lastly, the vocal sounded louder in the mix than usual, and stepped forward in the soundstage as well. High Frequencies 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 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. The Sennheiser HD400S is the successor of the Sennheiser HD 4.20! And as such, it has a great build quality, is comfortable on the head, and fits within a comfortable budget. But how does it sound? Let’s take a closer look with this Sennheiser HD400S Review! A Great Value! – Sennheiser HD400S Review In the Box
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. Although you can’t call the fit luxurious, the earpads were perfectly comfortable and unobtrusive on my ears. And it’s got a snug feel, while avoiding being too tight on the head. I also wear glasses, and the cans didn’t tilt them in any direction. Sound isolation is less than fantastic, though it will kill a little ambient hum.

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. With their large ear pads, the HD400S’s fit around your ears rather than simply sitting on top of them. This and the padded headband make them comfortable for longer listening sessions. For their size, they’re also surprisingly light. The HD 400S presents a reasonably spacious soundstage. These cans also convey a nice amount of width, height and depth for the price. And there was good precision in terms of instrument placement. You may not feel like you’re floating in a constellation of sound, but there’s definitely a sense of dimension. SUMMARY Sennheiser has done it again. The HD 400S performs well beyond its price range and is one of the better budget model headphones I’ve tried. It has very few bells and whistles and offers a simple means of listening that still delivers amazing clarity and quality. If you need a good first pair of headphones or need something that you can take out of the house, then the HD 400S is definitely for you. Placing the headphones on my head, they have a comfortable yet secure clamping force. Additionally, on the underside of the headband is a thin piece of padding. This padding is coated in a soft rubber or silicone material. As a result, the headphones stay fixed in place. Earcups
