My wife, son (4 years old), and I were biking today for a few hours. In order to keep my son's interest and hopefully build a love of cycling I try to point out fun stuff as we roll along. He also likes to co-create stories. Both of these things keep him from getting bored on long rides but it is really tough to yell back and forth. He is so soft spoken I end up craning my head around and am worried about getting in an accident. My wife wants to get some hands-free radios. I have done a little research and learned about VOX and seen some headsets on Amazon.

It would seem that with the radios I already own Motorola Talkabouts (1x T250 and 2x T6400 for what it is worth) I could just get some headsets and be good to go.

Curious if anyone has tried this and what the pitfalls might be? I can think of several (road noise messing up VOX, getting good audio, etc)

Thanks!
