This intercom proved amazing among our EUC community - not only it allows you to use your phone and listen to music with clear voices even on higher speeds, but it also allows connecting these intercoms to network up to 8 persons and have a radio chat in radius of up to 2000m, during this chat any user can still receive calls and connect back to chat.  This thing is useful if you ride alone, but if you ride in a group - priceless.
