Apologies if this has been asked before. Did a search but didn't find anything. I also downloaded the User manual but it doesn't seem to mention it. I have been lent a Sena smh10 r intercom. Intercom works great and i Have paired it with my zumo and iPhone 4S and it all seems to work great. Certainly a lot better than my old scala set. My question is when listening to music via Bluetooth from my phone is it possible to add my wife's headset, do she can hear the music as well. Any info appreciated.
