I want to use my cell phone while riding my Busa. Where can I buy a system or helmet microphone and voice activated microphone to use in an full face helmet. Something small and confortable. My friend and I tried to squeezze our helmets on with store bough mics and earbuds they did not work well, sort of faded out when we entered the freeway. But, worked sort of good while sitting at lights and doing less than 35 mph on the streets. We both have sprint PCS phone and the connection is free anytime when we talk to one another. We just need to get a good helmet mic and ear phones installed in our helmets. Any help will do. Even if I can modify my helmet with....the stuff you can buy at best buy, or any place. Please let me know.
