I always wear earplugs, I value my hearing too much. So I have tried to get the five other riders in my office that ride to work regulary to at least try wearing them. I've used the analogy that was previously mentioned that it is like rolling the windows up on your cage. Needless to say I'm just the "BMW nut" that thinks too much about safety, wears protective gear, a full face helmet (fits correctly), and can't hear anything cause he has ear plugs in. Oh well, I'll have me hearing later in life and enjoy my rides more.
