Here comes my long review:
This helmet is durable and will protect your dome-piece.
It has a nice liner, and the bluetooth seems to be durable. The sound from speakers is really good.
The earpieces/speakers crush the cartilage in your ears... After 3 hours of wear, you'll want to take it off (which can really suck if it's 8 degrees out). I have a normal shaped-head (7 and 1/4 ball-cap) with normal ears... I mean, no one ever said to me "man, you have big/odd ears" (I would have taken note)...
The eyelet on the ear piece (that lines the headphone jack) will definitely need to be re-glued at some point.
I might have to return it, due to the ear pain...
