Short answer: the Sony ULT Field 1, if you are buying new. The Soundcore Motion 100 ranks higher than it (#45 vs #100 of 175 medium speakers, 3.7/5 vs 3.1/5) but is discontinued, so only consider it used; the Sony ULT Field 1 is still sold new at $138.
The Soundcore Motion 100 is the better-sounding pick. It supports LDAC Bluetooth, which the Sony ULT Field 1 lacks. It plays in stereo from a single unit, unlike the Sony ULT Field 1. The catch: Not very deep bass, slight distortion.
What the Sony ULT Field 1 does well: IP67 rated, survives drops and 1m submersion. Watch for: Upper midrange peak, rolled off treble.
Buy the Sony ULT Field 1, since the Soundcore Motion 100 is discontinued and only worth hunting down used.
