For a limited time, Aukey’s offering deals on a pair of water-resistant Bluetooth speakers that you can take to the beach, or even into the shower.

Honestly, the $22 model (with code AUDIO4M8) is your best bet here. It has two drivers instead of one, and much longer battery life than the tire-shaped model, but $15 is an awfully tempting price (with code AUDIO4M4) if your needs are pretty basic.
