In my opinion, SENA needs to make their basic technology better before expanding to newer formats with the same issues.
For instance, I just got the 10S.
It still takes about 1.5 to 2 seconds for the intercom to connect. I hit the jog button, wait, wait, wait and then maybe the intercom connects.
It makes conversation difficult if I'm trying to point out road hazard or a specific view from the bike. By the time the intercom connects, it can be too late.
Just my opinion, I could be wrong.
