Short answer: the Zealot S89. It ranks #16 of 73 boombox speakers by sound quality at $246.99; the Sony SRS-XG500 ranks #45 and costs $349, so there is not much of a tradeoff to weigh.
What the Zealot S89 offers: A great value for the bass performance, play time and max volume in the boombox class. Likely the same internals as the Zealot ZE21 Watch for: On the heavy side. A little rolled off up top and not that balanced through the rest of the range. Clarity isn’t as good as better speakers. Bass EQ is bloated and muddy sounding
What the Sony SRS-XG500 offers: 30 hour battery life; 10-min quick-charge gives 3 hours. Battery care function stops charging at 90% to extend longevity. IP66 water/dust resistant. Two USB-A ports (one charges devices), mic/guitar inputs, AUX. Party mode links 100+ speakers. Watch for: Thuddy upper bass, not as deep bass as others. Speaker will not remain at max volume and will turn itself down automatically.
Buy the Zealot S89. It ranks higher for sound quality than the Sony SRS-XG500 and costs less, so the other one has nothing left to offer.
