Have you ever heard of Shaking Baby Syndrome for Adults? Probably not, because it hasn t been invented, until now. eDimensional is releasing a set of force feedback headphones that will fulfill your desire to be punched in the head and have your brain bounced around the inside of your skull like a pinball machine. Overall these are some pretty good headphones, minus the whole shaking your head until your forget math, thing. They are noise-canceling, include a microphone, are nicely designed, and use an in-line controller to handle the volume and shaking intensity. A lot of good features for a moderately priced $49. Oh, the things you will do in the name of gaming.
