Short answer: the Ultimate Ears Everboom. It ranks #34 of 120 large speakers by sound quality, rated 3.9/5, at $149.99; the Sony ULT Field 5 ranks #59, rated 3.5/5, and costs $348, so there is not much of a tradeoff to weigh.
The case for the Sony ULT Field 5: IP67 rated, dustproof and water resistant. Set against that: Bass not as deep as others in the category, and sound quality overall is just okay.
What the Ultimate Ears Everboom gets right: This speaker may move around as we get better sound samples. Set against that: Has an upper bass boost and is tuned warm with rolled off treble.
Buy the Ultimate Ears Everboom. It is rated higher for sound quality than the Sony ULT Field 5 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
