I have just started to wear them on long journeys, I dont bother for my normal 30 minute commute.
A lot depends on your helmet too, I find my Shoei has a lot more wind noise than the Aria before it.
After close to 30 years riding without earplugs, although by no means deaf I do have some odd hearing difficulties, I find it difficult to separate the dialogue from the background in movies and tv progs, and have to concentrate on conversations in a noisy enviroment, though that might just be old age
