With the LX-R3, you can call hands-free on your Bluetooth mobile phone, listen to 
stereo music or voice instructions of GPS navigations by Bluetooth wirelessly, and 
have intercom conversations in full duplex with a passenger or multi-pair up to 3 
riders in a small group and talk between any 2 of them in a range of 1000M (3,280 
feet) distance.

following profiles: Headset Profile, Hands-Free Profile (HFP), Advanced Audio 
Distribution Profile (A2DP). Please check with the manufacturers of other devices to 
determine their compatibility with this headset. 
Superior audio fidelity has been achieved with our wide-fidelity, non-ported and 
ultra-slim helmet speakers. This headset also provides the industry's best combination 
of wind and ambient noise reduction with the miniature boom microphone. 
Main unit is powered by a rechargeable Lithium Ion/Polymer power cell providing
