Short answer: the LG Xboom Go PL5, though neither ranks well in its class. It ranks #119 of 144 medium speakers by sound quality, rated 2.4/5, at $179; the Ultimate Ears Megaboom 4 ranks #139, 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 144 medium speakers; for better sound, the Earfun Uboom L ranks #1 at $49.79.
Why pick the LG Xboom Go PL5: 18 hour battery life; IPX5 rated. Watch for: Barely any bass.
The case for the Ultimate Ears Megaboom 4: IP67 rated, floats, and finally uses USB-C charging. The catch: A lot of distortion at higher volumes.
Buy the LG Xboom Go PL5. 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.
