Short answer: the Bose Soundlink Mini 2. It ranks #55 of 136 medium speakers by sound quality at $184; the Ultimate Ears Megaboom 4 ranks #132 and costs $200, which makes this an easy call rather than a real tradeoff.
What the Bose Soundlink Mini 2 offers: Compact aluminum build feels sturdy and dense. ~10 hour battery life; can pair to two devices at once and remembers up to 8. Watch for: Boosted upper bass like most Bose speakers. Upper treble rolled off. Bass is 2db less boosted than the Mini. Bass doesn’t go as deep as others. Failures of the mainboard are common.
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
