Short answer: the LG Xboom Grab. It ranks #106 of 177 medium speakers by sound quality, rated 3.0/5, at $100.98; the Ultimate Ears Megaboom 4 ranks #171, rated 2.1/5, and costs $200, which makes this an easy call rather than a real tradeoff.
Why pick the Ultimate Ears Megaboom 4: A tough waterproof speaker that floats, with USB-C charging, a long battery and PartyUp linking. Watch for: A lot of distortion at higher volumes.
The LG Xboom Grab is the better-sounding, lighter pick. A rugged waterproof speaker with elastic mounting straps, a long 20 hour battery, multipoint pairing and app room calibration. At 1.5 lbs (680 g) it weighs much less than the Ultimate Ears Megaboom 4 at 2.4 lbs (1.1 kg). It supports AAC Bluetooth, which the Ultimate Ears Megaboom 4 lacks. The tradeoff: Bass extension not as deep as the top speakers.
Buy the LG Xboom Grab. It is rated higher for sound quality than the Ultimate Ears Megaboom 4 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
