Short answer: the B&O Beosound A1 3rd gen on measured sound quality, the Sony ULT Field 3 on price. The B&O Beosound A1 3rd gen ranks #18 of 142 medium speakers at $381.52. The Sony ULT Field 3 ranks #60 at $138, $243.52 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 B&O Beosound A1 3rd gen offers: Longer battery than the 2nd gen (~24 hours at sensible volumes). IP67 rated with a serviceable, replaceable battery - the first Bluetooth speaker with Cradle to Cradle certification. Multipoint connectivity and aptX Adaptive. Watch for: Distorts easier than the 2nd gen with deeper bass. Dipped area in the upper mids. Not as deep of bass as the 2nd gen
