Short answer: the Sony ULT Field 1 if sound quality matters most, the Oontz Angle 3 Ultra if price matters most. The Sony ULT Field 1 ranks #86 of 150 medium speakers, rated 3.1/5, at $138. The Oontz Angle 3 Ultra ranks #135, rated 2.2/5, at $39.99, $98.01 cheaper.
What the Sony ULT Field 1 does well: IP67 rated, survives drops and 1m submersion. The catch: Upper midrange peak, rolled off treble.
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 Sony ULT Field 1 if sound quality is the priority over the price, or the Oontz Angle 3 Ultra if the price is the priority over sound quality.
There is a real battery-life gap here: the Oontz Angle 3 Ultra is rated for 20 hours, the Sony ULT Field 1 only 12 hours.
