That's exactly how my wife and I use them with the addition of aFreewire for myself so I can monitor my Ham Radio that is wired through the bike intercom. The 20s is a bit quirky at times but usually works well in the situation you describe.I'm in the same boat as LEBoyd. I want to pair my phone to my head set and my wifes to hers. So how can we talk to each other without pushing an intercom button? I also want to run my Zumo 550 and have it only feed directions into my headset and and be able for each of us to listen to our own music in our own headsets. Is this possible with the Sena 20 EVO??
