Zealot ZE01 vs Sony ULT Field 7

Last updated: August 18, 2026

Short answer: the Zealot ZE01. It ranks #25 of 73 boombox speakers by sound quality at $126.02; the Sony ULT Field 7 ranks #40 and costs $400, so there is not much of a tradeoff to weigh.

What the Zealot ZE01 gets right: Appears to be the same internals as the S95. The catch: A little rolled off up top and not that balanced through the rest of the range.

The case for the Sony ULT Field 7: Better sounding than the XG500. The tradeoff: Still not as deep bass as the top ranked speakers.

Buy the Zealot ZE01. It ranks higher for sound quality than the Sony ULT Field 7 and costs less, so there is no real case for the other one.
