Short answer: the JBL Flip 5. It ranks #62 of 136 medium speakers by sound quality at $64.97; the Sony ULT Field 1 ranks #76 and costs $98, which makes this an easy call rather than a real tradeoff.
What the JBL Flip 5 offers: Compact and light (1.1 lb) with a carry lanyard. Charges via USB-C, topping off in about 2.5 hours. IP67 rated. Watch for: Not stereo. Boosted upper bass. Piercing sound when turned up. Peaky lower treble at higher volumes.
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 JBL Flip 5. It ranks higher for sound quality than the Sony ULT Field 1 and costs less, so there is no real case for the other one.
