My g/f and I have the latest Cardo PackTalk Bold units with the JBL speakers. She doesn't usually like talking to me anyway, so she can't figure out why she should use the damned comm system. Still, it does the job, and has all the same mesh connectivity and in groups, enables each person to serve as a bit of an antenna, bouncing signal from front to rear riders, and as "friends" of the network come into range, they're automatically connected, etc. etc. as the Sena units, but honestly, I am pretty underwhelmed by it. The sound quality, when listening to music is mediocre, and at highway speeds, if my g/f is riding more than a few car lengths away, it becomes difficult to hear one another. Between the pair of them, there's quite a few bucks invested and it absolutely does not seem worth it to me.
