Short answer: the W-King D8 Mini, though neither ranks well in its class. It ranks #111 of 144 medium speakers by sound quality, rated 2.6/5, at $38.93; the Oontz Angle 3 Ultra ranks #129, rated 2.2/5, and costs $39.99, so there is little reason to consider the other one. 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.
Why pick the W-King D8 Mini: 30W output with switchable indoor/outdoor EQ modes. The catch: Recessed midrange, harsh treble.
Why pick the Oontz Angle 3 Ultra: 20+ hour battery life - some reviewers see 22-24 hours at 50% volume. The tradeoff: Very little bass with horrible upper bass thud at higher levels.
Buy the W-King D8 Mini. It is rated higher for sound quality than the Oontz Angle 3 Ultra and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
