What
I've always rode with ear plugs in myself. It makes riding more enjoyable in my opinion. It also helps me stay focused on the road and others as opposed to the constant wind noise.
Been wearing ear plugs since I started riding in the '80s.
Unfortunately, I'm already screwed! Between riding and work, my hearing has been long gone. I wear buds and try to keep the music low to get both affects of noise protection but in the back of my mind I know it's too late.
