The quality is very good, it filters out the sounds around.
Good connextion with my cell phone and my PC can use for Skype and MSN.
Especially it is very light when I do jogging is really handy, it holds well over my ears and wireless, it's total freedom!
But the only weak point is that the manual is in English, I put a little time to understand it, but all the Bluetooth headsets are about the same.
This helmet has a really great value for money, it is even better than the very expensive bluetooth headset Jabra I was offered last year.
Recommend !!!!!!!!
