Short answer: the Ultimate Ears Wonderboom 2, though neither ranks well in its class. It ranks #108 of 164 medium speakers by sound quality (rated 2.9/5) at $80 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 2. It is rated higher for sound quality, and the Tribit Stormbox is discontinued, so it is only available used.
If battery life is a priority, the Tribit Stormbox is rated for 20 hours versus 12 hours for the Ultimate Ears Wonderboom 2.

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 Discontinued; Tribit has retired it, superseded by the Stormbox 2.

Ultimate Ears Wonderboom 2: $80 Amazon eBay
Newer model: the Ultimate Ears Wonderboom 4, ranked higher, rated 2.9/5.
Pros: IP67 rated and floats. Compact and light enough to toss in a bag. Measured bass extension of 82Hz (-10dB).
Cons: Not stereo, barely any bass, recessed treble. Slightly boosted 93Hz upper bass Dip at 9kHz. You can tell from the micro USB that they are just feeding you the same crap hardware over and over, this is inexcusable for a product released in 2019. Not technically a 360 speaker, only front and rear.
