Okay, here goes. I have a Sena 10C that is at least 2 years old and almost from day 1 I was never pleased with the sound quality so i’m thinking of upgrading. I guess there are 3 main suppliers, Sena, Cardo and J&M. Upon examining all three online Cardo is the only one that talks extensively about sound quality having partnered with JBL. My biggest requirement for a headset is sound quality. I generally ride alone with my wife so communicating with other riders miles apart does not interest me. Keeping in mind I am mainly concerned with good perhaps great sound, what have others found does the job and does it well?
