Quiet Helmet Suggestions

Does anyone have any bright ideas on helmets that are quieter than others?
I got a new one last winter (Shark RSF2i) and its louder than my old cheapy AGV. I tried Mal's Shoei Diabolic on the weekend and it wasn't much better.
Mine makes my ears ring after about half hour and I've resorted to earplugs but hate them. Even the soft foamy work ones hurt after a while.
Any suggestions appreciated
