Sennheiser HD 400S Over-Ear Headphone with Mic

  • Renowned Sennheiser sound quality for a unique listening experience.

  • Built-in microphone and remote for call and music control.

  • Closed-back around-ear headphones reduce unwanted background noise for your comfort.

  • Lightweight, foldable headphones for easy on-the-go storage.




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.

Inline remote with mic

Featuring a one-button smart remote on the cable, the HD400S lets you take control of your music and calls. Play, pause and skip your music and accept or drop calls – all at the touch of a button. Tapped twice, you can also call on Siri or Google Assistant for voice guidance instructions.

Sennheiser sound

Using large Sennheiser drive units, the HD400S provide a rich, evenly balanced sound with a powerful bass. Using closed backs, they also keep out background noise – letting you hear more detail.

Surround yourself in music

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.

Foldable and convenient

The foldable design makes these headphones easy to store in your bag when not in use. A single-sided cable and angled 3.5mm plug also makes for a more comfortable connection when your music device is in your top pocket.

Take music and calls in comfort, with the Sennheiser HD400S.
