Charise D.wrote a review of Red Hifi Subwoofer System Helmet on January 27, 2010
I wasn't really looking for an mp3 playing helmet, but this one was the best price at the time so I bought it. It keeps your head warm, and I do feel much more confident with something to protect my head. There also isn't a gap with my Scott goggles.
The only complaint I have about this product is that the subwoofer ear pads do end up hurting my ears a lot after 4 hours of snowboarding. They feel fine up until then though. Well that, and my head looks slightly like a bowling ball, but that couldn't have been helped.
