Short answer: the Oontz Angle 3 Ultra, though neither ranks well in its class. It ranks #129 of 144 medium speakers by sound quality, rated 2.2/5, at $39.99; the Ultimate Ears Megaboom 4 ranks #139, rated 2.1/5, and costs $200, which makes this an easy call rather than a real tradeoff. Both are rated below 3.0/5 among the 144 medium speakers, and the Earfun Uboom L, ranked #1 at $49.79, is a better place to start if sound quality matters.
Why pick the Oontz Angle 3 Ultra: 20+ hour battery life - some reviewers see 22-24 hours at 50% volume. The tradeoff: Very little bass with horrible upper bass thud at higher levels.
Why pick the Ultimate Ears Megaboom 4: IP67 rated, floats, and finally uses USB-C charging. The tradeoff: A lot of distortion at higher volumes.
Buy the Oontz Angle 3 Ultra. It is rated higher for sound quality than the Ultimate Ears Megaboom 4 and costs less, so only choose the other one for a particular feature it does better.
