Short answer: the Zealot S95. It ranks #37 of 112 boombox speakers by sound quality, rated 3.7/5, at $157.41; the Yeahbox Sonic Boom Max 3 ranks #59, rated 3.2/5, and costs $228.99, which makes this an easy call rather than a real tradeoff.
Why pick 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 catch: There is limited independent testing and the water/dust rating is reported inconsistently across listings.
The Zealot S95 is the better-sounding, lighter pick. An affordable stereo boombox with water resistance, a power bank output and linking for up to 100 speakers. At 11.3 lbs (5.11 kg) it weighs noticeably less than the Yeahbox Sonic Boom Max 3 at 16.8 lbs (7.64 kg). The catch: A little rolled off up top and not that balanced through the rest of the range.
Buy the Zealot S95. It is rated higher for sound quality than the Yeahbox Sonic Boom Max 3 and costs less, so only choose the other one for a particular feature it does better.
