Short answer: the Ultimate Ears Wonderboom 4, though neither ranks well in its class. It ranks #106 of 164 medium speakers by sound quality (rated 2.9/5) at $78.95 and is still sold new; the Tribit Stormbox ranks #116 (rated 2.8/5) and is discontinued, so it is only an option used. Both are rated below 3.0/5 among the 164 medium speakers, so if sound quality matters, consider the Earfun Uboom L instead, ranked #2 at $49.79.
Buy the Ultimate Ears Wonderboom 4. It is rated higher for sound quality, and the Tribit Stormbox is discontinued, so it is only available used.

The Two Speakers In Full
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 Discontinued; Tribit has retired it, superseded by the Stormbox 2.

Older models: the Ultimate Ears Wonderboom 3 (ranked lower, rated 2.9/5), the Ultimate Ears Wonderboom 2 (ranked lower, rated 2.9/5) and the Ultimate Ears Wonderboom (ranked lower, rated 2.9/5).
Pros: Small size.
