Short answer: the Soundcore Boom 3i. It ranks #27 of 136 medium speakers by sound quality at $110; the Ultimate Ears Megaboom 4 ranks #132 and costs $200, so there is not much of a tradeoff to weigh.
What the Soundcore Boom 3i offers: Looks to be designed as a direct competitor to the Charge 5 with a very similar sound profile, warm tuned with boosted bass. Better value for the money than the Charge 5. Watch for: Not quite as good as a Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close. An earlier firmware version had some bass distortion, update your firmware in the Soundcore App
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
Buy the Soundcore Boom 3i. It ranks higher for sound quality than the Ultimate Ears Megaboom 4 and costs less, so the other one has nothing left to offer.
The Ultimate Ears Megaboom 4 is not a sound-quality pick. It sits near the bottom of the 136 medium speakers; there are better options higher up.
