I'm looking to purchase a new helmet with bluetooth already installed. One of the local BMW dealers is now selling Velmar helmets. I tried one on and liked it. One of my problems was that the salesperson was not very knowledgeable about the bluetooth option. In this months MOA Mag., in the advertisement, it states that it can operate up to 10 hours on a charge. This does not seem very long. Is there a way to charge it while riding. Is this ten hours of standby or useage. How about other helmets, like the Nolan-103. Thanks in acvance.
