I bought the U1 helmet so I can listen to music and when need, you the Mesh network to communicate with other riders in my group.  It wasn't until I contacted support did, I find out that music sharing is not an option on Cycle helmets. "Our bike helmets do not support the Music Sharing feature. While the helmets allow you to listen to music and use communication features independently, they are not designed to share audio playback between connected headsets.     I apologize for any inconvenience this may cause. "  

This would be a great feature to add to the cycle helmets.
