Pros: Very light and very comfortable, quite good quality of sound for such a small wireless headset, with bass.
Cons: Cannot adjust the fitting, so for a few people the fit may not work. Volume control is strange, you like it or not.
Summary: With a computer running OSX the headset worked like a charm, and worked great with Skype. One annoyance is that the bluetooth headset binds in Mono mode by default (on OSX), so you have to disconnect and select manually Stereo. Quite an annoyance if you have to do it often.
