Short answer: the Sony ULT Field 3 on measured sound quality, the Oontz Angle 3 Ultra on price. The Sony ULT Field 3 ranks #64 of 150 medium speakers, rated 3.4/5, at $208. The Oontz Angle 3 Ultra ranks #135, rated 2.2/5, at $39.99, $168.01 cheaper.
Why pick the Sony ULT Field 3: IP67 rated, dustproof and water resistant. Watch for: Sounds a bit hollow, a bit boosted in the treble.
What the Oontz Angle 3 Ultra does well: 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 Sony ULT Field 3 when sound quality outweighs the price for you, and the Oontz Angle 3 Ultra when the price outweighs sound quality instead.

The Two Speakers In Full
Sony ULT Field 3: $208.00 Amazon eBay
Older models: the Sony XB33 (ranked lower, rated 3.4/5), the Sony SRS-XE300 (ranked lower, rated 2.8/5) and the Sony SRS-XB30 (ranked lower, rated 2.6/5).
Pros: IP67 rated, dustproof and water resistant. 24 hour battery life. App with 10-band EQ. Party Connect with up to 100 speakers. USB-C in/out for charging your phone.
Cons: Sounds a bit hollow, a bit boosted in the treble. Custom EQ and the ULT bass-boost button can’t be used together: turning on ULT disables the EQ. Bass is very weak with ULT off. Lost to the JBL Charge 6 in a side-by-side comparison despite being the larger speaker.
