Short answer: the Oontz Angle 3, though neither ranks well in its class. Both are rated 2.1/5 for sound quality (#174 and #173 of 179 medium speakers), and the Oontz Angle 3 costs $19.98 against $200 for the Ultimate Ears Megaboom 4, and with sound quality even, the cheaper one is the better buy. Both are rated below 3.0/5 among the 179 medium speakers, so if sound quality matters, consider the EarFun Uboom L instead, ranked #2 at $49.79.
The Ultimate Ears Megaboom 4 is the longer-running, tougher choice. A tough waterproof speaker that floats, with USB-C charging, a long battery and PartyUp linking. It is rated for 20 hours of battery against 14 for the Oontz Angle 3. It is rated IP67 against IPX5 for the Oontz Angle 3. It charges over USB-C rather than Micro USB. Watch for: A lot of distortion at higher volumes.
The Oontz Angle 3 is the lighter pick. A very cheap splash resistant speaker with an aux input for casual use around the house. At 1.3 lbs (580 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.
Buy the Oontz Angle 3. Both are rated the same for sound quality, and it costs $180.02 less than the Ultimate Ears Megaboom 4.
