Overall, very nice helmet. Started out very tight at the cheeks but after a few days of wear the overly tight feel went away. Two weeks of wear and it fits perfectly. The size chart has me as a medium and that is what I got. Face shield works well, stays in detents. The tinted integrated shield is a great feature and works as advertised but it does add a very slight bit of distortion (not enough to be a problem, I use it all the time). Quiet/loud? I don't have anything to compare it to but it doesn't strike me as being particularly quiet, I wear ear plugs for highway riding. I like the graphics but they could cut back a little on the HJC logos.

HJC IS-17 Helmet Sizing
Wrap a tape measure horizontally around your forehead. Select the helmet that is the closest fit to that size. A helmet should fit snug on your head. If it moves while wearing, it is too large. If it is painful to wear, it is too small.
