Short answer: the Zealot ZE01. It ranks #38 of 112 boombox speakers by sound quality, rated 3.7/5, at $126.02; the Yeahbox Sonic Boom Max 3 ranks #59, rated 3.2/5, and costs $228.99, so there is not much of a tradeoff to weigh.
The case for the Yeahbox Sonic Boom Max 3: A large party speaker with powerful bass, a big fast charging battery and app EQ for outdoor parties. The tradeoff: There is limited independent testing and the water/dust rating is reported inconsistently across listings.
The Zealot ZE01 is the better-sounding, lighter pick. An affordable stereo boombox with a 40 hour battery, water resistance and a power bank for long days outdoors. At 13.2 lbs (6 kg) it weighs noticeably less than the Yeahbox Sonic Boom Max 3 at 16.8 lbs (7.64 kg). Watch for: A little rolled off up top and not that balanced through the rest of the range.
Buy the Zealot ZE01. It is rated higher for sound quality than the Yeahbox Sonic Boom Max 3 and costs less, which makes it the one to get unless you need something the other one does better.
