I have been really bothered by the loud wind noise in my helmets when "at speed" on the highway. Since my bikes don't have three foot tall wind screens, I can pick up quite a bit of noise while on the highway. Earplugs reduce some, but they are limited and work out after awhile. Hearing loss in sport bike riders is no joke, almost everyone I know who rides has some loss from riding. After a few hours in the saddle, the fatigue factor is nothing to be ignored either. I have a Bluetooth helmet and it works great! ...at a stoplight. At 55mph, fagetaboutit.
