Atlantic is introducing the Ego waterproof sound case for iPod during International CES at booth 7905. The Ego floats in the water and is designed to house fourth- and fifth-generation iPods. It is also a boombox featuring sealed waterproof speakers, sealed bass venting ports and sound powered by dual, full-range neodymium drivers. The silicone gasket and snap-locking closure is specially designed to seal in and protect iPods while still providing full feature access to the click wheel from the outside of the case through the waterproof click-wheel membrane. Powered by four AA batteries, the case has 30 hours of continuous playing time. The suggested retail is $199.
