Short answer: the LG Xboom Go PL5, though neither ranks well in its class. It ranks #149 of 179 medium speakers by sound quality, rated 2.4/5, at $289. The Ultimate Ears Megaboom 4 ranks #173, rated 2.1/5, at $200, $89 cheaper, a saving that is not big enough to make up the sound-quality gap. 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 LG Xboom Go PL5 is the lighter choice. A water resistant speaker with music synced LED lights, USB-C charging and Party Link for many speakers. At 1.4 lbs (640 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. It keeps a wired aux input, which the Ultimate Ears Megaboom 4 lacks. Watch for: Barely any bass.
The Ultimate Ears Megaboom 4 is the longer-running, tougher choice. A tough waterproof speaker that floats, with USB-C charging, a long battery and PartyUp linking. It is rated for 20 hours of battery against 15 for the LG Xboom Go PL5. It is rated IP67 against IPX5 for the LG Xboom Go PL5. The tradeoff: A lot of distortion at higher volumes.
Buy the LG Xboom Go PL5. It is rated higher for sound quality, and the $89 saving on the Ultimate Ears Megaboom 4 is not enough to make up the difference.
