I've had this earpiece for about a week, and so far, so good. I was a little concerned about how well people on the other end of the line would be able to hear me since the unit is so small and sits so far away from your mouth. But, everyone I've spoken to says they can hear me just fine. I'm also able to hear the other end of the conversation pretty well too. The adjustable volume control is useful in this regard.A couple of minor issues: (1) It's not the most comfortable earpiece in the world, and it feels like it's going to fall off at any time. (Although - to be honest - this has never happened, so maybe it's just something I need to get used to.)(2) I'm not crazy about the blinking blue light thing. Maybe people think it looks cool or something, but I'd rather not have something attached to my ear that incessantly flashes a bright blue light.
