Short answer: the JBL Charge 6, if you are buying new. The JBL Charge 4 ranks higher than the Ultimate Ears Wonderboom 2 (#63 vs #111 of 175 medium speakers) but is discontinued; its replacement, the JBL Charge 6, is rated 4.2/5 at $119.95 and is still sold new.

The JBL Charge 4 is the better-sounding, deeper-bass pick. Doubles as a power bank for charging phones/tablets. Its bass reaches about 54Hz 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 is rated for 20 hours of battery against 12 for the Ultimate Ears Wonderboom 2. Watch for: 1 Oval driver.
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 JBL Charge 4 at 2.1 lbs (960 g). The catch: Not stereo, barely any bass, recessed treble.
Buy the JBL Charge 6, the replacement for the discontinued JBL Charge 4; it is rated higher for sound quality than the Ultimate Ears Wonderboom 2.

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.
