Unless there is some super helmet out there that is very quiet with the wind whistling past at 80 mph, I don't see how you could listen to music at non damaging levels on the highway without being behind a large shield.
Foam ear plugs are a MUST with my CB shorty at highway speeds despite smooth air flow, but not with my CB + 4 x 2 "winter" shield.
