My riding buddies and I have been checking out bike to bike communication systems to use on our longer rides. We like the helmet mounted systems with Bluetooth allowing mp3 and cellphone hookup, long distance bike to bike communication, voice activation, and stereo earphones. I would prefer a system allowing me to use my earfuze earphones, so a jack allowing interchangeable earphones would be desirable; hardwired microphone/earphone setups would be a second choice for me. If I have to use a hardwired mic/ear setup, maybe Radio Shack has an adaptor that I could use to add mine in sequence. Do you have any suggestions or advice? Do you have any experience with these units?
