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. 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.
Sennheiser aimed to be balanced when designing the HD 400S. The bass range doesn’t leave me wanting more but also isn’t overpowering. It has a nice balance that works well with all genres. While bass parts tend to be more clear than warm, this is still very good for a headphone at this price. I was impressed by the lows and how well they were able to deliver clean and balanced bass. Mids 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 Unlike over-ears, they're smaller and more portable. You can bring them to the gym thanks to their IPX4 rating for resistance against water splashes. Thanks to their stability fin design, they'll stay in place during tough workouts, although their fin design can be a little uncomfortable depending on your ear shape. Their continuous battery life of over eight hours is great, and their carrying case supplies an additional three charges if needed.

Lineup
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. 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:
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.

Prices valid in stores (all including VAT) until close of business on 25th November 2023. (Some of these web prices are cheaper than in-store, so please mention that you've seen these offers online.) 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. 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
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. EarcupsAlthough 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.
