Short answer: the Soundcore Boom 3i. It ranks #31 of 175 medium speakers by sound quality, rated 4.0/5, at $118.99. The Ultimate Ears Wonderboom 2 ranks #111, rated 2.9/5, at $80, $38.99 cheaper, which does not close the gap in sound quality.
The Soundcore Boom 3i is the better-sounding, deeper-bass option. Looks to be designed as a direct competitor to the JBL Charge 5 with a very similar sound profile, warm tuned with boosted bass. Its bass reaches about 56Hz before falling 10dB, against 82Hz for the Ultimate Ears Wonderboom 2. It is rated for 16 hours of battery against 12 for the Ultimate Ears Wonderboom 2. It supports AAC Bluetooth, which the Ultimate Ears Wonderboom 2 lacks. Watch for: Not quite as good as a JBL Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.
The Ultimate Ears Wonderboom 2 is the lighter option. IP67 rated and floats. At 0.9 lbs (420 g) it weighs much less than the Soundcore Boom 3i at 1.7 lbs (783 g). The tradeoff: Not stereo, barely any bass, recessed treble.
Buy the Soundcore Boom 3i. It is rated higher for sound quality, and saving $38.99 with the Ultimate Ears Wonderboom 2 does not make up for the sound-quality gap.

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.
