Short answer: the Ultimate Ears Boom 3 for clearer highs, the Tribit Stormbox for stereo pairing and longer battery life, though neither ranks well in its class. The Stormbox is IPX7 with dual pairing for stereo, an excellent 20-hour battery and 97dB max volume, but it sounds muffled with a treble dip from 5kHz to 12kHz. The Boom 3 has crisp highs, stable Bluetooth and an IP67 floating shell. Both are rated below 3.0/5 among the 151 medium speakers; for better sound, the Earfun Uboom L ranks #1 at $49.79.
Buy the Ultimate Ears Boom 3. It is rated higher for sound quality; the Tribit Stormbox is no longer sold new.

The Two Speakers In Full
Ultimate Ears Boom 3: $134.99 Amazon eBay
Newer model: the Ultimate Ears Boom 4, ranked higher, rated 2.9/5.
Pros: Rich and warm bass without muddying mix, crisp highs, excellent 15-hour battery life, stable Bluetooth connectivity, IP67 rated and floats, rugged fabric shell, can pair up to 150 speakers via PartyUp. Measured bass extension of 91Hz (-10dB).
Cons: Not stereo, barely any bass, recessed treble. 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 2021. Lots of mentions of failing batteries on amazon. Not technically a 360 speaker, only front and rear.

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 Discontinued; Tribit has retired it, superseded by the Stormbox 2.
