Summary: I accept that (and for 200 quid they should be) good sound quality, however, when used as a headset for skype/mobile phones on calls etc. they are appalling. The mic is too far away from the mouth to be effective and the units bluetooth capability is really not very good at all, it wont consistently connect to my MAC Air, or android phone it keeps dropping off and says - connection failed!
Summary: I bought the headphone one year ago and the cable is already broken. When we pay that price, I feel it should last for longer. I precise I used it only with my desktop computer; so normal conditions. Disappointed!
