Anthony said:My wife and I both have a SENA SMH10B and they work great together. Both for listening to music, sharing music and for the intercom. I have also used it to pair with other SENA units and it worked great. I can't say if it will work for other companies units, but within SENA it works well. I want to upgrade to a newer SENA system so that I can pair with more people, but for now mine works great!
