Short answer: the Soundcore 3. It ranks #62 of 157 medium speakers by sound quality, rated 3.4/5, at $59.99; the Sony ULT Field 1 ranks #90, rated 3.1/5, and costs $138, so there is little reason to consider the other one.
The Soundcore 3 is the longer-running, lighter pick. Identical in acoustic design and performance to the retailer variant Soundcore Select 2. It is rated for 24 hours of battery against 12 for the Sony ULT Field 1. At 0.8 lbs (372 g) it weighs much less than the Sony ULT Field 1 at 1.4 lbs (650 g). It plays in stereo from a single unit, unlike the Sony ULT Field 1.
Why pick the Sony ULT Field 1: IP67 rated, survives drops and 1m submersion. The tradeoff: Upper midrange peak, rolled off treble.
Buy the Soundcore 3. It is rated higher for sound quality than the Sony ULT Field 1 and costs less, which makes it the one to get unless you need something the other one does better.
