A Cardo Packtalk Duo intercom set plus a spare Integrated Boom (we had 3 helmets) just use the 2 power sets to clip into the helmet mounted booms. Most parts still bagged and not used. In excellent condition and you can use it with up to 9 buddies plus a whole lot more techie type things including radio, have a look at the Cardo website. The boom mounting piece stuck to the helmet so replaced it with 3m dots which can be seen in the pic and are very sticky. Just used it on a trip to France with a mate who had a Schuberth SRC Headset and no problems. £300 includes postage, Pm me if interested Cheers Jim
