Short answer: the Xiaomi Sound Party. It ranks #19 of 134 medium speakers at $133.62; the Sony ULT Field 3 ranks #57 and costs $148, so there is not much of a tradeoff to weigh.
The case for the Sony ULT Field 3: IP67 rated, dustproof and water resistant. The tradeoff: Sounds a bit hollow, a bit boosted in the treble.
What the Xiaomi Sound Party gets right: Sounds pretty balanced overall, more neutral than the Charge 5. Nice passive radiator visual effect. The catch: Bass can sound slightly thuddy at high volume, 180hz peak.
Buy the Sony ULT Field 3 if the price matters more than the ranking. Buy the Xiaomi Sound Party if the ranking matters more than the price.
