I have the same helmet and I am so glad someone else is having this issue too because I thought I was going nuts. I bought this helmet because it was supposed to be one of the lightest and quietest helmets on the market. It is quiet but I get a slight ringing in my ears even with any brand ear plugs. Sometimes I wonder if it is a wind buffeting thing versus just noise. I don't know. I sometimes wonder if it could be caused by my Sena mounted on the side of my helmet. Maybe it is in a place that creates a wind frequency that makes my ears ring. Who knows.....
If you find something, please post. I've tried ear plugs from every vendor. Some are better than others. I've tried thicker padding in the helmet. No help. It doesn't happen all the time and it isn't a show stopper. But it is definitely there.
