10W Bluetooth speaker that is totally waterproof (if you seal it closed correctly). AudioFlood is the same company that sells the waterproof iPod.
Really good for use at the beach, by the pool, or on a boat. Also doubles as a power bank (USB out is 5V).
Connects via Bluetooth (has NFC), but also has AUX in, and can play from microSD card slot.
This is a lightning deal, so it expires today (at 6:30PM ET )
