Think audio's not that important to video games? Try playing Call of Duty on mute or kicking to the licks on Guitar Hero without any sound. Yeah, exactly. While much of the focus on video game sites is graphics quality, there's one site devoted to the way video games sound — Astro Gaming. Their line of wireless headsets makes every bullet zing, every level-up feel even more glorious and every ambient sound ring like a bell. In addition to headphones, Astro also sells gaming apparel, customizable tags, audio cables and, of course, microphones so all that trash-talking gets through crystal clear.
