Josh,
I've been talking to everyone and anyone that would listen about this exact subject. The guys from J&M say that it is illegal in 46 states so they see a demand. Big Ears Inc. says they have something in the works called "HALO". I don't know what it is but, it a helmetless intercom / radio interface. The problem is how to attach the noise-cancelling mic boom. Big Ears is a molded piece that fits into the ear for speakers but there is no way to attach the mic.
I actually went over to a buddy's this afternoon to try his CB mic w/ the Bluetooth. It works well! I placed a call, and had the speakers turned on, then communicated w/ the handheld mic. The person on the other end said it sounded fine. I think this is the route I'm going to go until there is a better solution. AJ
