Short answer: the Ultimate Ears Wonderboom 2, though neither ranks well in its class. It ranks #111 of 175 medium speakers by sound quality, rated 2.9/5, at $80; the Ultimate Ears Megaboom 4 ranks #170, rated 2.1/5, and costs $200, which makes this an easy call rather than a real tradeoff. Both are rated below 3.0/5 among the 175 medium speakers, so if sound quality matters, consider the EarFun Uboom L instead, ranked #2 at $49.79.
The Ultimate Ears Wonderboom 2 is the better-sounding, lighter option. IP67 rated and floats. At 0.9 lbs (420 g) it weighs much less than the Ultimate Ears Megaboom 4 at 2.4 lbs (1.1 kg). The catch: Not stereo, barely any bass, recessed treble.
The Ultimate Ears Megaboom 4 is the longer-running choice. IP67 rated, floats, and finally uses USB-C charging. It is rated for 20 hours of battery against 12 for the Ultimate Ears Wonderboom 2. It links with other speakers (PartyUp up to 50 speakers), which the Ultimate Ears Wonderboom 2 cannot. It has an adjustable EQ, which the Ultimate Ears Wonderboom 2 lacks. The tradeoff: A lot of distortion at higher volumes.
Buy the Ultimate Ears Wonderboom 2. It is rated higher for sound quality than the Ultimate Ears Megaboom 4 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

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.
