autocomm active 7 smart
does what it says on the box.
It's a few years old now .. bought at the bike show when they were doing the half price offers.
Normally use it just for takling to pillion but have tried it out with both MP3 player & mobile phone.
Works great.. very clear at all speeds with excellent noise cancelling.
using the mobile was strange as both of you can join in the conversation and hear/talk.
As I've not used the starcomm I can't offer a comparison.
When I bought mine I made the final decision on price as I couldn't see any product features important to me that made one more attractive than the other.
