Short answer: the LG Xboom Grab. It ranks #82 of 136 medium speakers by sound quality at $88.42; the Ultimate Ears Boom 4 ranks #88 and costs $105, so there is not much of a tradeoff to weigh.
On the LG Xboom Grab side: 20 hour battery life - longer than the JBL Flip 7 or UE Boom 4. IP67 rated with elastic mounting straps. The catch: Bass extension not as deep as the top speakers. Overpriced. This may move around in the rankings as we get better sound samples.
What the Ultimate Ears Boom 4 offers: IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. 15 hour battery. Set against that: Not much improvement over the old ones. Weak bass extension and thuddy bass.
Buy the LG Xboom Grab. It ranks higher for sound quality than the Ultimate Ears Boom 4 and costs less, so there is no real case for the other one.
