Sknet has developed RelacOn, a set of waterproof speakers for media players such as Apple's iPod. Users can open up the cover of RelacOn and connect a player via the stereo plug. Once tucked inside, a device is safe in water up to a depth of 30-feet, according to the company. Users must decide on playlist music before closing the lid, however, as the only dial accessible from the outside is a volume knob, according to Electronista. The speakers offer 800mW of power each, and are supplied by batteries providing 30 hours of playback. RelacOn is scheduled for shipment in Japan later this month for $40 in three colors which include pink, white, and marine blue.
