Short answer: the Tribit Stormbox for stereo and battery, the Wonderboom for floating, though neither ranks well in its class. The Stormbox is IPX7 water resistant, supports dual pairing for a stereo setup and claims excellent 20 hours of battery life plus 97dB max volume, but it sounds muffled with treble dips from 5kHz to 12kHz. The Wonderboom is IP67 rated and floats, but it is not stereo and has barely any bass and recessed treble, and it costs $79 against $68. Both are rated below 3.0/5 among the 157 medium speakers, and the Earfun Uboom L, ranked #1 at $49.79, is a better place to start if sound quality matters.
Buy the Ultimate Ears Wonderboom only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Earfun Uboom L instead.

Tribit Stormbox: $68 Discontinued eBay
Newer model: the Tribit Stormbox 2, ranked higher, rated 3/5.
Pros: IPX7 water resistant, dual pairing for stereo setup, excellent battery life (20 hours), instant on/off buttons, 97dB max volume. Measured bass extension of 52Hz (-10dB).
Cons: Muffled sounding, treble dips from 5kHz-12kHz. Listening from the front is the worst frequency response, lay it down facing up with xbass off for the smoothest response. Not technically a 360 speaker, only front and rear. Discontinued; Tribit has retired it, superseded by the Stormbox 2.
