Short answer: the Sony ULT Field 3. It ranks #57 of 136 medium speakers by sound quality at $148; the Ultimate Ears Megaboom 4 ranks #132 and costs $200, so there is not much of a tradeoff to weigh.
What the Sony ULT Field 3 offers: IP67 rated, dustproof and water resistant. 24 hour battery life. App with 10-band EQ. Party Connect with up to 100 speakers. USB-C in/out for charging your phone. Watch for: Sounds a bit hollow, a bit boosted in the treble. Custom EQ and the ULT bass-boost button can’t be used together - turning on ULT disables the EQ. Bass is very weak with ULT off. Lost to the JBL Charge 6 in a side-by-side comparison despite being the larger speaker.
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 Sony ULT Field 3. 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.
Skip the Ultimate Ears Megaboom 4 if sound quality matters to you. It ranks near the bottom of the 136 medium speakers.
