Great sound quality - both speaker and mic. If anything, the mic is too good...as in there is not noise filter but at least the other person can hear you. Range was good. I had it in my pocket and no problems. Very clear and loud - great for my worn ear drums. My only problem is that it lasted 2 days before the speaker started to rattle. I'm taking it back to the store but not sure if I want to chance getting another one...especially when it doesn't have noise canceling. Oh, as for the fit, it's perfect but that all depends on your ears. I hate it when people on here complain that it has a bad fit. We were all born with body parts ranging in sizes.
