I've been through a lot of headsets. Each one has issues with how well they work or how well they fit. I have a BlueAnt Z9 which fits pretty well but picks up noises like running water or shuffling paper and delivers them at ear-splitting levels to my caller. The Jawbone 2 is beautiful but doesn't fit because the required jaw contact is hard to maintain and you don't know until the caller says (again) that he can't hear you.
