It's an A2DP stereo Bluetooth 2.0 headset and Sennheiser claims 'audiophile sound quality' – the company certainly has plenty of experience when it comes to making earphones, that's for sure.
The headset gives you the basics when it comes to controlling your phone, allowing you to answer/end/reject, mic mute and transfer calls.
There are three different sizes of silicon ear sleeves for a perfect fit, and you can choose from USB, mains or in-car charging options. You'll also get a lanyard and a clothing clip in to the bargain.
Out now, the Sennheiser MM 200 Bluetooth stereo headset will set you back £100.
