Short answer: the Soundcore Boom 3i. It ranks #29 of 150 medium speakers by sound quality, rated 4.0/5, at $118.99. The Oontz Angle 3 Ultra ranks #135, rated 2.2/5, at $39.99, $79 cheaper, which does not close the gap in sound quality.
The case for the Soundcore Boom 3i: Looks to be designed as a direct competitor to the Charge 5 with a very similar sound profile, warm tuned with boosted bass. Watch for: Not quite as good as a Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.
Why pick the Oontz Angle 3 Ultra: 20+ hour battery life: some reviewers see 22-24 hours at 50% volume. Watch for: Very little bass with horrible upper bass thud at higher levels.
Buy the Soundcore Boom 3i. It is rated higher for sound quality, and the $79 you would save on the Oontz Angle 3 Ultra does not close the gap.
