Short answer: the Sony ULT Field 3. It ranks #75 of 175 medium speakers by sound quality (rated 3.4/5) at $208 and is still sold new; the Tribit Stormbox Mini ranks #148 (rated 2.4/5) and is discontinued, so it is only an option used. The Tribit Stormbox Mini’s replacement, the Tribit Stormbox Mini+, is rated 2.5/5 at $31.99.
The Sony ULT Field 3 is the better-sounding, longer-running choice. IP67 rated, dustproof and water resistant. It is rated for 24 hours of battery against 12 for the Tribit Stormbox Mini. It supports LDAC Bluetooth, which the Tribit Stormbox Mini lacks. It has an adjustable EQ, which the Tribit Stormbox Mini lacks. Watch for: Sounds a bit hollow, a bit boosted in the treble.
The Tribit Stormbox Mini is the lighter pick. IPX7 waterproof, excellent battery life (12 hours), RGB LED lighting, app support with AAC codec, true wireless stereo (TWS) capability, USB-C charging. At 1.6 lbs (708 g) it weighs much less than the Sony ULT Field 3 at 2.6 lbs (1.2 kg). It keeps a wired aux input, which the Sony ULT Field 3 lacks. The catch: Lacking quite a bit of bass.
Buy the Sony ULT Field 3. It is rated higher for sound quality, and the Tribit Stormbox Mini is discontinued, so it is only available used.

Same family: the Sony ULT Field 1 (smaller model, ranked lower, rated 3.1/5), the Sony ULT Field 7 (smaller model, rated 3.2/5), the Sony ULT Tower 10 (smaller model, rated 3.9/5), the Sony ULT Field 5 (larger model, rated 3.5/5), the Sony ULT Tower 5 (larger model, rated 4.5/5), the Sony ULT Tower 7 (larger model, rated 4.7/5), the Sony ULT Tower 9 (larger model, rated 4.2/5) and the Sony ULT Tower Max (larger model, rated 4.8/5).
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.
