I am using my Schuberth this year. The open face one so its inherently noisy but nice. Not used the CX3 for a few years and that cost 450 when i bought it in about 2007 and used it to do my Isle of Man rip in 2009.
So, maybe Schuberth is even better nearly 20 years on.
With my Thunderbird screen, i tilted it down using a 2 inch long bracket so the screen was lower and tilted more so wind went over my head. That fixed most of the wind noise
