Just a word of warning to anyone considering the 30K. If you have the Bluetooth intercom turned on, nothing else works, no music, no nothing. You have to manually turn the intercom on and off to use it, and when it is on, all music or any other audio inputs cease.
I'd like to know if Sena is even aware of this. I'm ready to put mine back in the box and return them. This problem makes them pretty much useless to me.
