Short answer: the Sony ULT Field 1 on measured sound quality, the Tribit Stormbox Mini+ on price. The Sony ULT Field 1 ranks #100 of 175 medium speakers, rated 3.1/5, at $138. The Tribit Stormbox Mini+ ranks #142, rated 2.5/5, at $31.99, $106.01 cheaper.
The Sony ULT Field 1 is the better-sounding option. IP67 rated, survives drops and 1m submersion. Watch for: Upper midrange peak, rolled off treble.
Why pick the Tribit Stormbox Mini+: IPX7 waterproof, app support with EQ presets and AAC codec, true wireless stereo (TWS) capability, USB-C charging, built-in mic for calls, AUX input, microSD card playback. It keeps a wired aux input, which the Sony ULT Field 1 lacks. It plays in stereo from a single unit, unlike the Sony ULT Field 1. Watch for: Not a great sounding speaker, really weak bass.
