Atlantic has announced its iceBar Waterproof nano Speaker Case, sibling to the EGO Waterproof Sound Case for iPod. The iceBar is a completely waterproof, floating, two-speaker system for first- and second generation iPod nanos. Features include a flip-out leg, nylon wrist strap, a miniature “buoy,” shatterproof polycarbonate body, Click Wheel membrane for control of the nano when it’s secured in the case, and external mute and power buttons. The iceBar is powered by three AAA batteries, which provide enough power for 18 continuous hours of music. The iceBar Waterproof nano Speaker Case will sell for $70 when it becomes available this holiday season.
