Short answer: the Ultimate Ears Boom 4, though neither ranks well in its class. It ranks #93 of 144 medium speakers by sound quality, rated 2.9/5, at $119.99. The LG Xboom XG5 ranks #120, rated 2.4/5, at $99, $20.99 cheaper, a saving that is not big enough to make up the sound-quality gap. 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 Ultimate Ears Boom 4: IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. Watch for: Not much improvement over the old ones.
What the LG Xboom XG5 does well: IP67 rated. Watch for: Peaky midrange, rolled off treble.
Buy the Ultimate Ears Boom 4. It is rated higher for sound quality, and the $20.99 saving on the LG Xboom XG5 is not enough to make up the difference.
