Earplugs
Earplugs reduce the sustained wind noise inside a helmet at highway speed, which is a major source of rider fatigue.
What are earplugs for on a motorcycle? Earplugs cut the sustained wind noise that builds inside a helmet at highway speed — noise that is present whether or not the bike has loud pipes, because it is generated by air moving around the helmet. Riders report less fatigue at the end of a long day with them in, and many say they hear traffic more clearly because the wind roar is out of the way. Rules on wearing earplugs while driving or riding vary by state, so check your own.
