This sturdy case protects an any-generation iPod from water, dust, and crushing forces while providing clear audio from its built-in speaker. It is constructed from polycarbonate covered with a shock-absorbing rubber shell on all four sides and corners. The case closes using two locking latches that keep both halves shut (and the o-ring sealed tight), making it 100% waterproof, even after being dropped or knocked. Its full-range, forward-firing 3-watt speaker provides crisp sound; with external volume control, good enough for use poolside, at the beach, or camping. An internal pouch secures an iPod; a built-in audio cable connects an iPod to the speaker inside the case. It remains fully buoyant up to its maximum load of 8 oz., so it can hold keys, credit cards, and IDs in addition to an iPod or any other MP3 player or smartphone. Three AA batteries (required) power the speaker for up to 30 hours. 7 1/4" L x 4 1/2" W x 2 1/2" D (3/4 lb.)
