Very disappointed in the new SM10. My BlueTooth music source must be connected to it by cable and I still must choose between music and intercom. My existing set up of one headset by BlueTooth and the other by 3.5mm dongle is better, as I still have full BT control, and a lot cheaper. In its present form the SM10 is not worth the money.
Hopefully, Sena will be able to improve the unit so that we can have voice comms with music in the background.
