Short answer: the Ultimate Ears Wonderboom 2, if you are buying new. The Soundcore Boost “upgraded” 2021 ranks higher than it (#5 vs #111 of 175 medium speakers, 4.4/5 vs 2.9/5) but is discontinued, so only consider it used; the Ultimate Ears Wonderboom 2 is still sold new at $80.
The Soundcore Boost “upgraded” 2021 is the better-sounding, deeper-bass option. A very neutral good sounding inexpensive small speaker with quite deep bass for the size. Its bass reaches about 56Hz before falling 10dB, against 82Hz for the Ultimate Ears Wonderboom 2. Alan Ross Reviews measured it at 99dB at full volume, against 88dB for the Ultimate Ears Wonderboom 2. It has an adjustable EQ, which the Ultimate Ears Wonderboom 2 lacks. The catch: Slight DSP tuning issue which makes bass get lighter at times at very low volumes, examples in oluv’s video.
The Ultimate Ears Wonderboom 2 is the lighter pick. IP67 rated and floats. At 0.9 lbs (420 g) it weighs noticeably less than the Soundcore Boost “upgraded” 2021 at 1.3 lbs (590 g). Watch for: Not stereo, barely any bass, recessed treble.
Buy the Ultimate Ears Wonderboom 2 new; the Soundcore Boost “upgraded” 2021 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.
