Short answer: the Ultimate Ears Boom 3 if sound quality matters most, the Tribit Stormbox Mini+ if price matters most, though neither ranks well in its class. The Ultimate Ears Boom 3 ranks #114 of 175 medium speakers, rated 2.9/5, at $134.99. The Tribit Stormbox Mini+ ranks #142, rated 2.5/5, at $31.99, $103 cheaper. Both are rated below 3.0/5 among the 175 medium speakers, and the EarFun Uboom L, ranked #2 at $49.79, is a better place to start if sound quality matters.
The Ultimate Ears Boom 3 is the better-sounding choice. 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. The catch: Not stereo, barely any bass, recessed treble.
The case for the Tribit Stormbox Mini+: IPX7 waterproof, app support with EQ presets and AAC codec, true wireless stereo (TWS) capability, USB-C charging, built-in mic for calls, AUX input, microSD card playback. It supports AAC Bluetooth, which the Ultimate Ears Boom 3 lacks. It keeps a wired aux input, which the Ultimate Ears Boom 3 lacks. It charges over USB-C rather than Micro USB. The tradeoff: Not a great sounding speaker, really weak bass.
Buy the Ultimate Ears Boom 3 when sound quality outweighs the price for you, and the Tribit Stormbox Mini+ when the price outweighs sound quality instead.

Ultimate Ears Boom 3: $134.99 Amazon $134.99 eBay
Newer model: the Ultimate Ears Boom 4, ranked higher, rated 2.9/5, released Jun 2024. See every Ultimate Ears Wonderboom, Boom and Megaboom generation.
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.
