Jake Wwrote a review of Red Hifi Subwoofer System Helmet on December 3, 2008
The sound on this helmet is super awesome. The sub woofer is a very nice addition and the mute/volume keys are ver convenient. The one downfall is this helmet is way big. It is very lite but when getting in and out of a full gondola your head feels huge. I would recommend checking this helmet out in person before purchasing to make sure you are ok with the size.
