It's the Scala Rider Q2 Sue - supposed to have a 500 metre range which we didn't really test last night. I have a Schuberth S1 lid which is very quiet and suits the intercom so I'm OK up to about 70 or 80mph. My son's lid is also a Schuberth (although the more sportier version) which is also reasonably quiet so I can natter with him when he's pillion. Works the same with SatNav, Phone, MP3 but also has inbuilt FM radio if you're into that kind of thing.

I bought mine from the US on the internet since the dollar/pound exchange rate is so good it's worth the wait. You still have to pay VAT but for the two I bought I still saved 60 quid.
