Short answer: the Tribit Stormbox Flow. It ranks #62 of 175 medium speakers by sound quality, rated 3.5/5, at $79.99; the Sony ULT Field 1 ranks #100, rated 3.1/5, and costs $138, which makes this an easy call rather than a real tradeoff.
The Tribit Stormbox Flow is the better-sounding, longer-running choice. Up to 30 hours of battery life: roughly double most rivals (~20-24 hrs with XBass on). It is rated for 30 hours of battery against 12 for the Sony ULT Field 1. Watch for: Midrange and bass are weirdly recessed about 4db below 700Hz.
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 Tribit Stormbox Flow. It is rated higher for sound quality than the Sony ULT Field 1 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Speakers In Full
Tribit Stormbox Flow: $79.99 Tribit $79.99 eBay
Same family: the Tribit Stormbox Micro 2 (smaller model, rated 4.5/5), the Tribit Stormbox Pro (larger model, ranked higher, rated 3.7/5) and the Tribit Stormbox Blast (larger model, rated 4.5/5). See every Tribit Stormbox generation.
Pros: Up to 30 hours of battery life: roughly double most rivals (~20-24 hrs with XBass on). IP67 rated with a loose handle for carrying/hanging. Pairs with a second Flow for stereo; USB-C port charges your phone too. Measured bass extension of 47Hz (-10dB).
Cons: Not stereo. Midrange and bass are weirdly recessed about 4db below 700Hz. You need xbass mode for it to not sound like a clock radio with missing bass. You also can’t turn up the bass enough in the custom EQ modes to get it neutral, so it will sound bass light. Firmware 1.2.3 fixes the distortion issues with xbass mode on, but bass still sounds wobbly and uncontrolled.
