Short answer: the Oontz Angle 3 Ultra, though neither ranks well in its class. It ranks #163 of 179 medium speakers by sound quality, rated 2.2/5, at $39.99; the Ultimate Ears Megaboom 4 ranks #173, 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 179 medium speakers, and the EarFun Uboom L, ranked #2 at $49.79, is a better place to start if sound quality matters.
The Oontz Angle 3 Ultra is the lighter choice. A cheap, very light waterproof speaker with a long battery and plenty of features for the money. At 0.9 lbs (400 g) it weighs much less than the Ultimate Ears Megaboom 4 at 2.4 lbs (1.1 kg). It keeps a wired aux input, which the Ultimate Ears Megaboom 4 lacks. It plays in stereo from a single unit, unlike the Ultimate Ears Megaboom 4. The catch: Very little bass with horrible upper bass thud at higher levels.
Why pick the Ultimate Ears Megaboom 4: A tough waterproof speaker that floats, with USB-C charging, a long battery and PartyUp linking. 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.
