Speakers that use SurfaceSound technology to pump music through the surface they're sitting on aren't exactly anything new, but TuneBug has managed to put a slightly different spin on the idea with its new Shake speaker -- which, as TuneBug so eloquently puts it, will finally give you some "Music 4 UR Melon." While that may or may not also work directly on your skull, it will definitely work with a range of helmets, including bike helmets with the included TuneStrap, or skate helmets with the included Gecko Mount. Look for it to be available by the end of the month for $119.95, along with the more conventional Vibe SurfaceSound speaker, which will set you back $69.99.
