I just recieved my new ed set and istalled them in my Scorpion 3/4 helmet. I own a 2011 Ultra Classic, and based on what I was reading here, was fearful the headsets wouldn't work.
I can tell you that Ed was very patient with me and recommended the necessary equipment (which required no extra intallation by me) to make the EdSet compatable with my sstem on the Harley.
I am ver happy with the experience and cannot wait for my first loing ride (this weekend) to get some time with the new speakers.
