I really think the sound quality of two cans and a string is better than this headset. Voices are muddy and muffled at best. It sounds like the person you're talking to is holding a towel over their mouth.It has ZERO noise cancellation. The person on the other end hears every little sound in the background. If it's a prolonged sound like water running, or wind, forget it.It fits my ear fine. Big deal. It sounds horrible.This is my first bluetooth headset and I'm extremely disappointed. If this is as good as they get then they've got a LONG way to go. This is a step back into the audio quality of a 1970's hand held transistor radio. Not even THAT good.Don't buy the hype. This thing stinks.
