Balanced sound surprise for a small price, bass response without saturating the spectrum, a problem often encountered by entry-level helmets in my opinion. It does not fully isolate outside noise and not nexerce very strong pressure on the head (if wearing glasses, means if we want to use it on the subway). I have however benefited as 2 months since he broke at the articulated joint arch - atrium, whereas it was folded and stowed in a backpack. In short, an unbeatable value side helmet, but to care for fragile.
