Short answer: the Ultimate Ears Wonderboom 4, though neither ranks well in its class. It ranks #89 of 144 medium speakers by sound quality, rated 2.9/5, at $59.99; the LG Xboom XG5 ranks #120, rated 2.4/5, and costs $99, 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.
What the Ultimate Ears Wonderboom 4 does well: Small size. Watch for: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
What the LG Xboom XG5 does well: IP67 rated. The catch: Peaky midrange, rolled off treble.
Buy the Ultimate Ears Wonderboom 4. It is rated higher for sound quality than the LG Xboom XG5 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
