Life doesn’t have a soundtrack (which can be good or bad), but if you’d like to add a soundtrack to your activities the Tunebug Shake will help get you started or as the company touts it “Music 4 UR Melon.” 
This mini-external sound generator (don’t think of it as just another speaker), mounts to your skate/snowboard or bike helmet. The Tunebug Shake features a 3.5mm audio jack, as well as Bluetooth technology. It runs on a LiPoly battery that can last longer likely than your legs! The Tunebug shake is available now for $119.95.
