I've still got dead zones near me. If I were cycling with someone, and we wanted to chat on headsets, there's at least a few places I might ride where we'd hit dead air. If we're on different networks, then we both need coverage to communicate with cellular.

Might be more reasonable to use higher bandwidth, lower latency codecs over bluetooth as well?



For this use case, old fashioned radio is a lot more reliable.


Quite likely, but then you need to carry that radio. And probably still carry a phone in case you split up and want to communicate.


You raised reliability issue, you've got a solution, now you're moving a goalpost and raising a convenience argument.

Decide which one is it.

PS Motorola talkabout T62 or T42 - small, light, reliable. Retevis h777: sturdy, reliable. You can just drop them in the bag.
