For long time i am proud owner of an Sennheisser MM550 Bluetooth Headset. Right now i found out that my Lenovo Miix 2 is the first Full Windows device that recognise it without any problems. Music from VLC will straight go to the Headset if you connect it. Thats nice. I will do some tests with skype and hangout with this to see how it will to there. stay tuned.
