Short answer: the Sony ULT Field 3, since the Tribit Stormbox Mini+ is called not a great sounding speaker. The Tribit offers IPX7, app EQ presets, AAC, TWS pairing, USB-C and a mic at $29.99, but its bass is really weak. The Sony is IP67 rated and dustproof and water resistant at $138, yet it sounds a bit hollow with boosted treble.
On the Sony ULT Field 3 side: IP67 rated, dustproof and water resistant. Set against that: Sounds a bit hollow, a bit boosted in the treble.
The case for 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. Set against that: Not a great sounding speaker, really weak bass.
Buy the Sony ULT Field 3 when sound quality outweighs the price for you, and the Tribit Stormbox Mini+ when the price outweighs sound quality instead.
Skip the Tribit Stormbox Mini+ if sound quality matters to you. It ranks near the bottom of the 142 medium speakers.
Battery life favors the Sony ULT Field 3: rated for 24 hours against 12 hours for the Tribit Stormbox Mini+.

The Two Speakers In Full
Sony ULT Field 3: $138.00 Amazon eBay
Pros: IP67 rated, dustproof and water resistant. 24 hour battery life. App with 10-band EQ. Party Connect with up to 100 speakers. USB-C in/out for charging your phone.
Cons: Sounds a bit hollow, a bit boosted in the treble. Custom EQ and the ULT bass-boost button can’t be used together - turning on ULT disables the EQ. Bass is very weak with ULT off. Lost to the JBL Charge 6 in a side-by-side comparison despite being the larger speaker.
