I purchased a used bike w/a J&M radio and Zumo linked to an ARAI helmet. The audio quality in the helmet is terrible but, no fear, it didn't fit and needed a new one anyway. I purchased a NOLAN from J&M w/ the best set up they have and the quality is terrible in a different way! One has no high-end and the other is ALL high-end. Anyone know how to EQ these things or know of a better headset?
