Short answer: the Tribit Stormbox 2 is the better sounding small speaker; the Ultimate Ears Boom 3 wins on rugged features. The Boom 3 is IP67 rated, floats, pairs up to 150 speakers via PartyUp and runs 15 hours, but the notes say it is not stereo with barely any bass and recessed treble. The Tribit is a little better sounding than the Stormbox 1 with less rolled off treble, though its side drivers roll the treble off face on.
Buy the Tribit Stormbox 2. It is rated higher for sound quality than the Ultimate Ears Boom 3 and costs less, so only choose the other one for a particular feature it does better.
If battery life is a priority, the Tribit Stormbox 2 is rated for 24 hours versus 15 hours for the Ultimate Ears Boom 3.

Older model: the Tribit Stormbox (ranked lower, rated 2.8/5).
Pros: A little better sounding than the Stormbox 1, less of a rolled off treble. Keep Xbass on for best frequency response.
Cons: Drivers on the side, so it will have a rolled off treble listening to it face on.

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.
