These are not really the same size class, and that is the honest framing here. The Tribit Stormbox Micro 3 ranks #6 of 47 small speakers by sound quality at $59.99; the Sony ULT Field 3 ranks #61 of 144 medium speakers by sound quality at $138.
What the Tribit Stormbox Micro 3 does well: Tribit Stormbox Micro 3 uses 48mm NdFeB driver with coaxial passive radiators. The tradeoff: Bass is limited by its 62Hz specification.
The case for the Sony ULT Field 3: IP67 rated, dustproof and water resistant. The catch: Sounds a bit hollow, a bit boosted in the treble.
Buy the Tribit Stormbox Micro 3 at $59.99 if you want a small speaker. Buy the Sony ULT Field 3 at $138 if you want a medium speaker instead.

Older models: the Tribit Stormbox Micro 2 (rated 4.5/5) and the Tribit Stormbox Micro (rated 4.3/5).

PartyUp and Auracast party mode link multiple speakers. Measured bass extension of 62Hz (-10dB).
Cons: Bass is limited by its 62Hz specification. Bass is thuddy and distorted by default and needs EQ.

Sony ULT Field 3: $138.00 Amazon eBay
Older models: the Sony XB33 (rated 3.4/5), the Sony SRS-XE300 (rated 2.8/5) and the Sony SRS-XB30 (rated 2.6/5).
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.
