Just tried a set of these... two of us, on off-road bikes... used the intercom, "radio" and phones. Seemed to work just fine.... batteries lasted all day, intercom range is about 1/2 to 3/4 mile on the forest dirt roads, maybe longer on a staight hiway, phone connects quickly, there are some voice commands but didn't use them, with gloves it's hard to get the touch for the options so sometimes the "radio" came on suddenly.... pretty expensive! Might be great paired with a radar detector, phone (with music), and an intercom???? Might just be another distraction... I probably oughta focus on driving since no one else does????
