Audiophile, Premium, Best In-Class, Sennheiser

The award winning Sennheiser MM 400-X on-ear Bluetooth headphones offer you the best of both worlds: the freedom of wireless Bluetooth music and the high quality sound that Sennheiser is known for. These premium on-ear headphones don't skimp on the internals. Utilizing the latest aptX technology, an advanced audio circuit to deliver true high-fidelity sound over Bluetooth, the MM 400-X headphones don't disappoint. Sennheiser's patented Duofol™ diaphragms provide you with incredibly detailed, crystal clear sound. To go along with the convenience of Bluetooth and awesome Sennheiser sound, the MM 400-X's were carefully engineered to provide you with the ultimate in comfort during even the longest listening sessions. Premium soft padded headphone cushions and an adjustable headband ensure these headphones allow nearly any user to wear these headphones discomfort-free for hours on end.

Enjoy Bluetooth Freedom with the Sennheiser MM 400-X HeadphonesBluetooth Freedom

No matter how carefully you wrap and store cables, they somehow find a way to get tangled up. Headphone cables are no different, and the MM 400-X headphones were designed with Bluetooth to give you that wireless freedom. Combined with the built-in microphone, these headphones are perfect for getting lost in your music and managing your calls without getting ever tangled up in that mess of wires again.

Integrated Controls for Easy UseOn-Board Controls

When you're in a groove the last thing you want to do is pull out your phone to adjust the volume or skip a track. These headphones have eliminated that inconvenience by integrating volume, track and phone call controls into the right earcup to give you total direct control of your device. You'll never have dig your phone out of your pocket, purse or backpack to control your music or answer a call again.

Collapsible Headphones for Easy PortabilityPortability

Let's face it, as much as we would all like to never take off our headphones, there comes a time where we just have to. While the MM 400-X's are best served being listened to, Sennheiser engineered them with collapsing hinges with those non-use times in mind as well. When collapsed, these headphones are incredibly compact, making them both easy to transport and store.
