Short answer: the Sony ULT Field 3 on measured sound quality, the Tribit Xsound Surf on price. The Sony ULT Field 3 ranks #57 of 136 medium speakers at $148. The Tribit Xsound Surf ranks #79 at $26, $122 cheaper.
What the Sony ULT Field 3 offers: 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. Watch for: 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.
What the Tribit Xsound Surf offers: Rugged rubberized frame with a metal grille. About 20% louder than the XSound Go at the same volume. IPX7 rated, USB-C charging, and pairs with a second Surf for stereo. Watch for: Bass doesn’t go as deep as others, strange midrange peaks
Buy the Sony ULT Field 3 if sound quality is the priority over the price, or the Tribit Xsound Surf if the price is the priority over sound quality.
There is a real battery-life gap here: the Sony ULT Field 3 is rated for 24 hours, the Tribit Xsound Surf only 10 hours.
