Short answer: the Ultimate Ears Wonderboom 4, though neither ranks well in its class. It ranks #95 of 150 medium speakers by sound quality, rated 2.9/5, at $59.99. The Oontz Angle 3 ranks #146, rated 2.1/5, at $28, $31.99 cheaper, not enough of a saving to outweigh the sound-quality gap. Both are rated below 3.0/5 among the 150 medium speakers, so if sound quality matters, consider the Earfun Uboom L instead, ranked #1 at $49.79.
What the Ultimate Ears Wonderboom 4 does well: Small size. The catch: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
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. Watch for: Bass is limited by its 138Hz specification.
Buy the Ultimate Ears Wonderboom 4. It is rated higher for sound quality, and the $31.99 saving on the Oontz Angle 3 is not enough to make up the difference.
