Short answer: the LG Xboom Grab. It ranks #85 of 142 medium speakers by sound quality at $97.73; the Ultimate Ears Megaboom 4 ranks #137 and costs $200, which makes this an easy call rather than a real tradeoff.
What the Ultimate Ears Megaboom 4 offers: IP67 rated, floats, and finally uses USB-C charging. 20 hour battery life. ‘PartyUp’ feature syncs multiple UE speakers together. Watch for: A lot of distortion at higher volumes. Rolled off treble. Not very loud. They really screwed this up
What the LG Xboom Grab offers: 20 hour battery life - longer than the JBL Flip 7 or UE Boom 4. IP67 rated with elastic mounting straps. App unlocks AI room calibration, EQ, and light-strip customization; multipoint pairing. Watch for: Bass extension not as deep as the top speakers. Overpriced. This may move around in the rankings as we get better sound samples
Buy the LG Xboom Grab. It ranks higher for sound quality than the Ultimate Ears Megaboom 4 and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the Ultimate Ears Megaboom 4. It ranks near the bottom of the 142 medium speakers, so look higher up the list instead.
