I purchased a set of the Q2-Cardo-Scala-Rider-multiset headsets after seeing champos set on a ride weekend, after doing some research into where to purchase them I got them cheaper from mobile outlet on the Gold Coast, the shipping was cheap and fast.
I have since used mine on nearly every ride since purchasing them and have transferred one set in and out of 5 different helmets now. I ridden and communicated with Salina on the same bike and bike to bike with Crash and Dan. They have been through rain on the caves to caves etc ad never missed a beat. Only once have the gone flat and that was towards the end of day one on the OBT’s biggest weekend out after 12.5 hrs of use. The recharging is fast and easy so its never a problem.
The real life range is about 400m direct line in the bush and we have found pretty well always stay in contact even at really high speed and tight going wooded areas. They are also a great safety device when there are two of you or when leading a ride.
I have since helped 3 people purchase the Q2-Cardo-Scala-Rider-multiset-motorcycle-Bluetooth-kits from mobile outlet on the Gold Coast and all are very happy.
They have blue tooth capability for your phone and are very clear when riding and on the phone, they also have an FM radio and can accept your MP3 player
Beware of the cheaper early versions on Ebay that dont have all these features
