Short answer: the Sony ULT Field 1 for better sound quality, the Oontz Angle 3 for the lower price. The Sony ULT Field 1 ranks #86 of 150 medium speakers, rated 3.1/5, at $138. The Oontz Angle 3 ranks #146, rated 2.1/5, at $28, $110 cheaper.
The case for the Sony ULT Field 1: IP67 rated, survives drops and 1m submersion. The tradeoff: Upper midrange peak, rolled off treble.
The case for the Oontz Angle 3: At 580 g, Oontz Angle 3 combines 2x precision acoustic drivers + 1x passive bass radiator with Bluetooth and aux. The catch: Bass is limited by its 138Hz specification.
Buy the Sony ULT Field 1 when sound quality outweighs the price for you, and the Oontz Angle 3 when the price outweighs sound quality instead.
