Short answer: the Xiaomi Sound Outdoor. It ranks #44 of 144 medium speakers by sound quality, rated 3.7/5, at $54.99. The Oontz Angle 3 Ultra ranks #129, rated 2.2/5, at $39.99, $15 cheaper, which does not close the gap in sound quality.
What the Xiaomi Sound Outdoor does well: Xiaomi Sound Outdoor uses 20W woofer, 10W tweeter + 2x passive radiators. The catch: Its 60Hz - 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size.
The case for 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 Xiaomi Sound Outdoor. It is rated higher for sound quality, and the $15 saving on the Oontz Angle 3 Ultra is not enough to make up the difference.

The Two Speakers In Full
Xiaomi Sound Outdoor: $54.99 Amazon eBay
Pros: Xiaomi Sound Outdoor uses 20W woofer, 10W tweeter + 2x passive radiators. Its 597 g, claimed 12 hours (Manufacturer specified) battery life, IP67 protection and mono playback make it a practical option for its intended room or portable use. A decent sounding speaker for its size.
Cons: Its 60Hz - 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size. There is no companion app. No EQ adjustment. Boosted bass that gets somewhat uncontrolled at high levels.
