I've had Arai, and Shoei helmets and have come to the conclusion there is no such thing as a quiet full face helmet. I've ridden with ear plugs for over 20 years and ear plugs will cut the noise on any helmet. It's not just the helmet but other factors that contribute also to wind noise. Windshield shape, head winds. For me it's a lot more enjoyable ride wearing ear plugs. If you're looking for a quiet helmet the Bell RS1 that I have now is the quietest full face helmet I've owned.
