Short answer: the Ultimate Ears Wonderboom 4, though neither ranks well in its class. It ranks #109 of 179 medium speakers by sound quality, rated 2.9/5, at $64.99; the LG Xboom XG5 ranks #150, 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 179 medium speakers; for better sound, the EarFun Uboom L ranks #2 at $49.79.
The Ultimate Ears Wonderboom 4 is the better-sounding, lighter option. A small, tough waterproof speaker with a strap loop and USB-C charging, easy to clip on a bag for outdoor trips. At 0.9 lbs (420 g) it weighs much less than the LG Xboom XG5 at 1.5 lbs (680 g). Watch for: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
What the LG Xboom XG5 does well: A waterproof speaker with a long tested battery, fast USB-C charging, app EQ, lights and an aux input. It supports AAC Bluetooth, which the Ultimate Ears Wonderboom 4 lacks. It keeps a wired aux input, which the Ultimate Ears Wonderboom 4 lacks. It links with other speakers (Wireless Party Link, up to 10 speakers), which the Ultimate Ears Wonderboom 4 cannot. The tradeoff: 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.
