Short answer: the Ultimate Ears Wonderboom 2, if you are buying new. The Bose Soundlink Mini ranks higher than it (#74 vs #111 of 175 medium speakers, 3.4/5 vs 2.9/5) but is discontinued, so only consider it used; the Ultimate Ears Wonderboom 2 is still sold new at $80.
The Bose Soundlink Mini is the better-sounding, deeper-bass choice. Compact aluminum build feels sturdy and dense. Its bass reaches about 58Hz before falling 10dB, against 82Hz for the Ultimate Ears Wonderboom 2. It keeps a wired aux input, which the Ultimate Ears Wonderboom 2 lacks. It plays in stereo from a single unit, unlike the Ultimate Ears Wonderboom 2. The tradeoff: Boosted upper bass like most Bose speakers.
The Ultimate Ears Wonderboom 2 is the longer-running, lighter pick. IP67 rated and floats. It is rated for 12 hours of battery against 7 for the Bose Soundlink Mini. At 0.9 lbs (420 g) it weighs much less than the Bose Soundlink Mini at 1.5 lbs (680 g). It is rated IP67, while the Bose Soundlink Mini has no water resistance. The tradeoff: Not stereo, barely any bass, recessed treble.
Buy the Ultimate Ears Wonderboom 2 new; the Bose Soundlink Mini is no longer sold new, so it only makes sense as a used find.

Ultimate Ears Wonderboom 2: $80 Amazon $80 eBay
Newer model: the Ultimate Ears Wonderboom 4, ranked higher, rated 2.9/5, released Jun 2024.
Older model: the Ultimate Ears Wonderboom (ranked lower, rated 2.9/5). See every Ultimate Ears Wonderboom, Boom and Megaboom generation.
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.
