Update: This discussion made me realize that I can connect my OpenComm either for voice or music. In the BT music mode the music rendition is quite pleasant, but bidirectional voice communication is absent. In the voice mode, the music quality is bad, but one can talk. Maybe this is obvious for everyone, but has been a discovery for me. For the bike and phone I will stay with the wired connection where everything is of a reasonable good quality all at once including getting input from 3 devices.
