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 Ultra ranks #135, rated 2.2/5, at $39.99, $20 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.
The case for the Ultimate Ears Wonderboom 4: Small size. The tradeoff: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
Why pick the Oontz Angle 3 Ultra: 20+ hour battery life: some reviewers see 22-24 hours at 50% volume. The catch: Very little bass with horrible upper bass thud at higher levels.
Buy the Ultimate Ears Wonderboom 4. It is rated higher for sound quality, and saving $20 with the Oontz Angle 3 Ultra does not make up for the sound-quality gap.
