Short answer: the Sony ULT Field 3 for features, the Tribit Xsound Plus 2 for price and weight. The Field 3 is IP67 rated with a 24-hour battery, a 10-band EQ app, Party Connect for up to 100 speakers and USB-C in and out, though it sounds a bit hollow and boosted in the treble. The Plus 2 is cheap and light but boosts treble and bass, peaks at 320Hz, dips at 500Hz and turns slappy in Xbass mode.
Buy the Tribit Xsound Plus 2. It is rated higher for sound quality than the Sony ULT Field 3 and costs less, so only choose the other one for a particular feature it does better.

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