Short answer: the Soundcore Motion 100. It ranks #39 of 136 medium speakers by sound quality at $47; the Sony ULT Field 1 ranks #76 and costs $98, so there is little reason to consider the other one.
What the Soundcore Motion 100 offers: Use Oluv’s EQ for the flattest response Watch for: Not very deep bass, slight distortion. Real-world battery falls well short of the 12-hour claim at higher volumes (closer to 4 hours at max). Charging takes about 5 hours; no charge-out for other devices.
What the Sony ULT Field 1 offers: IP67 rated, survives drops and 1m submersion. Real-world battery around 28+ hours with ULT (bass boost) mode off. Stereo-pairs with a second ULT Field 1. Watch for: Upper midrange peak, rolled off treble
Buy the Soundcore Motion 100. It ranks higher for sound quality than the Sony ULT Field 1 and costs less, which settles it without a real tradeoff to make.
