Short answer: the Ultimate Ears Wonderboom 4, though neither ranks well in its class. It ranks #95 of 150 medium speakers by sound quality, rated 2.9/5, at $59.99; the LG Xboom Go PL5 ranks #125, rated 2.4/5, and costs $179, so there is not much of a tradeoff to weigh. Both are rated below 3.0/5 among the 150 medium speakers, and the Earfun Uboom L, ranked #1 at $49.79, is a better place to start if sound quality matters.
What the Ultimate Ears Wonderboom 4 does well: Small size. The catch: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
What the LG Xboom Go PL5 does well: 18 hour battery life; IPX5 rated. Watch for: Barely any bass.
Buy the Ultimate Ears Wonderboom 4. It is rated higher for sound quality than the LG Xboom Go PL5 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
