I have had all three, J&M , Ed Sets. and currently Air Rider factory fit into a Nolan helmet, not one was any better than the other for sound quality, But!!!!!!!! j&m has the better, heavier , cord between the bike and the helmet, they last two to one over the other brands, but this would not stop from using the other brands, cords are not that expensive, and are just casualties of the wear and tear of a lot of riding.
