I just installed a comm-set (J&M 629 Elites) into one of my helmets. (Shoei RJ Platinum ¾ open-face) This is the first helmet headset I have ever had. Wow! What a GREAT sound. Even better then I was expecting. AND, I installed it myself. Well before iPods, MP3s, CD players and Walkmans I first started dreaming about something like this back in the ‘70s. I would ride my Triumph 650 imagining that I had my parents “cans” on listening to a record. Never could figure out how to mount and hook up the record player let alone keep it from skipping. Then I did not ride for over 25 years. Well now I am back and absolutely loving this headset. I have nothing but my iPod earbuds to compare it to but these 629s hold their own - I am very happy with the performance of this headset.
