Even though this is my first and only bluetooth headset, and some say I don't have anything to compare it to, this is by far one of the best, if not the best headset you can get here.When shopping for a headset I spent countless hours trying out headsets, I'm big on sound quality and for this headsets this is one of its biggest pluses.As far as for fitting, i haven't had any problem keeping in my ear, the only problem was putting it in the proper position so the sound of my voice could be picked up properly, once you find that perfect postion, people can hear you just fine and like I said the sound quality is amazing (to me at least)I would greatly recommend it.
