I got the Scala headsets for my wife and I to use, and partly because they have bike to bike range. I have to say I've not been that impressed. Getting the two headsets synced is a nightmare. When I did get them working the volume was fairly low so it was hard to hear her. I've also not found their support to be that fantastic.
I'm still trying to make a go of it with the Scala headset since I don't want to let them go to waste, but given my experience if I had it to do over I'd go a different way. Mind you, the situation I was dealing with was using them on a motorcycle that had not built in intercom. Given that the Goldwing does have one built in, I would probably go with the wired headset were I to do it now. The only thing it doesn't give is bike to bike, which isn't a big deal if you're not riding with another person on a motorcycle.
