Short answer: the Oontz Angle 3, though neither ranks well in its class. Both are rated 2.1/5 for sound quality (#140 and #139 of 144 medium speakers), and the Oontz Angle 3 costs $28 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 144 medium speakers, so if sound quality matters, consider the Earfun Uboom L instead, ranked #1 at $49.79.
What the Ultimate Ears Megaboom 4 does well: IP67 rated, floats, and finally uses USB-C charging. Watch for: A lot of distortion at higher volumes.
What the Oontz Angle 3 does well: At 580 g, Oontz Angle 3 combines 2x precision acoustic drivers + 1x passive bass radiator with Bluetooth and aux. The tradeoff: Bass is limited by its 138Hz specification.
Buy the Oontz Angle 3. Both are rated the same for sound quality, and it costs $172 less than the Ultimate Ears Megaboom 4.
