Sennheiser MM 400 Bluetooth

 

Get a unique sound and a superior clarity

Higher quality when it comes to the clarity of the sound and that of the bass. It provides wireless freedom and the Bluetooth technology allows telephone connection

The microphone is not properly functioning and there are often delays at the level of the Bluetooth technology. Also, there are some controls that are not compatible with iPhone

While you get the feeling that you are only using headphones from time to time, the Sennheiser MM 400 Bluetooth headset still makes a great investment for those who long searched for the device that delivers great sound quality. The invisible...

Sennheiser MM 400-X

 

Best wireless headphones, Awards 2012. A must-audition for owners of aptX-enabled phones and laptops

Very compact, portable design; tonnes of multimedia-friendly features; aptX for the best Bluetooth audio quality

Wired headphones still sound a bit better

The Sennheiser MM 400-X Bluetooth headphones offer true portability with excellent wired and wireless audio. At £179 they're not cheap but they feel comfortable and robust and boast sound that beats other Bluetooth headphones we've tested. The two-year...

Folding Bluetooth Headset : Sennheiser MM 400-X

 

Not everybody will appreciate your choice of music but by using a headset you can avoid upsetting others. A new Sennheiser allows you private listening without tying you to a fixed point.

Checking my records revealed that the last Sennheiser headset I looked at was the PX100-IIi model which could be folded to take up less space when not in use. Prior to that model I had also run the rule over the Sennheiser RS120. This particular model...
