OK, I was away for a few days at the Eastern Rendezvous, and so have not posted here yet. Here are some impressions:
First, the problem I'm having with bluetooth music breaking up: Sena replied to my support request by RMAing my units and sending new ones out last week. For all I know they'll be at my house when I finally get there some time today. They've also been very communicative and helpful, which is all good in my book.
Second, audio comms: My bike is small and a bit loud on the highway, and the Sena headset suffers a bit here when compared to the very clear noise cancellation of my old Autocom unit. I absolutely love the convenience and ease of the Sena units, though, so it's a bit of a toss-up.
Battery life has been excellent, easily making it through long days on the road.
