Short answer: the Bose Soundlink Mini. It ranks #56 of 136 medium speakers by sound quality at $128.67; the Sony ULT Field 3 ranks #57 and costs $148, so there is not much of a tradeoff to weigh.
What the Bose Soundlink Mini offers: Compact aluminum build feels sturdy and dense. Watch for: Boosted upper bass like most Bose speakers.
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.

If battery life is a priority, the Sony ULT Field 3 is rated for 24 hours versus 10 hours for the Bose Soundlink Mini.

Sony ULT Field 3: $148 Amazon
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.
