I have Shoei RF-900. However, like others said, it doesn't matter what helmet as the quietes one is still too noisy. Gotta use earplugs. I may recommend the blue ones from any drugstore with as much damping as possible. The best I found are the blue ones with 33 db noise reduction. Buy a pack for a few bucks, and that will last you for a long time. I use a pair for a few weeks. There is like a dozen or two in the pack.
The first time I put earplugs in, I was like: "Wow! That is nice and quiet. I can really concentrate on riding, and not having ringing in my ear after the ride."
