Short answer: the W-King D8 Mini, though neither ranks well in its class. It ranks #136 of 179 medium speakers by sound quality, rated 2.6/5, at $49.99. The Oontz Angle 3 Ultra ranks #163, rated 2.2/5, at $39.99, $10 cheaper, which does not close the gap in sound quality. 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 W-King D8 Mini is the better-sounding, deeper-bass choice. An inexpensive water resistant stereo speaker with indoor and outdoor sound modes and a long rated battery. Its bass reaches about 63Hz before falling 10dB, against 90Hz for the Oontz Angle 3 Ultra. The tradeoff: Recessed midrange, harsh treble.
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 W-King D8 Mini at 2.8 lbs (1.26 kg). The catch: Very little bass with horrible upper bass thud at higher levels.
Buy the W-King D8 Mini. It is rated higher for sound quality, and saving $10 with the Oontz Angle 3 Ultra does not make up for the sound-quality gap.
