I’ve had the Autocom system for a few years now and I’m on my third kit. The first kit was on my Gixer that was stolen (subsequent Gixer was then fitted with another Autocom system) and then I “upgraded” the system last year to the newer one. My wife and I both ride bikes and it’s great for us to chat away to each other, but from time to time when she has to jump on my bike then we can just use the rider to pillion functionality. The newer system with the auto adjusting volume control is a must and when listening to your MP3 player or similar around town the volume is nice and quiet.
We also have friends who use the same kit and I believe they’ve never had any problems with it. If you do want to look at getting a system then phone Autocom up and ask to speak to Rich or Paul as they’ll be able to help you out.
These two you mention, are they wireless? Myself I got two Interphone Bluetooth sets, you can buy extra ‘headsets’ and brackets so you can actually fit up 2, 3 or 4 different helmets, but then use the same 2 Bluetooth reciever units with them.
I think for a pair you’re probably looking around £240, but they are great. It’s hard up over 60mph, but you can pretty much tell what the person is saying. The added benefit is, when using just your own helmet, you can patch your phone or satnav into your helmet
