CL-X6 by chance? That's what I'm wearing now, to replace an older Thor-branded HJC. Wind noise in the new CL-X6 is much more than the old helmet. However, I've found that the vast majority of that wind noise comes from the top vent; plugging this vent (with a finger to prove the point, or a piece of tape to actually ride with) makes the helmet much, much quieter. I'm one of the earplugs every ride gang, more so because of wind noise on the highway, and because of intake/exhaust noise on the trail. I work in industry, so I'm well trained in the chronic effects of noise on hearing. Hearing...you'll never miss it until it's gone. And you'll never get it back once it is.
