Don't waste your money
If the only riding you do is in town at less than 35 mph, these will work great. Any faster than that and your voice transmission becomes a garbled mess. This is with a Nolan modular helmet. My brother suffered the same fate with the full face version on his helmet (don't know what helmet he has off hand.) The only time we were able to use them as advertised was sitting at the gas pumps, figuring out our next route. We used these with a good Cobra GMRS radio, and a very nice Motorola GMRS. Very nice looking, well built set up, but the performance just isn't there.
