Short answer: the JBL Partybox 130 for better sound quality, the Zealot PT21 for the lower price. The JBL Partybox 130 ranks #5 of 46 party speakers at $420.03. The Zealot PT21 ranks #12 at $216.73, $203.30 cheaper.
What the Zealot PT21 gets right: Dual 166mm woofers deliver quite deep bass for the price, plus a bundled wireless microphone with echo effect built in for karaoke, for about half the price. The catch: app-based EQ customization doesn’t appear to be fully supported yet.
On the JBL Partybox 130 side: Quite neutral sound, plus a removable battery, handle, and wheels. The tradeoff: boomier and less clear than the smaller Partybox 120, and JBL’s daisy-chain only works with other JBL speakers.
Buy the Zealot PT21 if the price matters more than sound quality. Buy the JBL Partybox 130 if sound quality matters more than the price.

The Two Speakers In Full
Zealot PT21: $216.73 Aliexpress
Pros: Dual 166mm woofers and 200W output in a lighter, more compact body than the ZE41, with a bundled wireless microphone and echo effect built in for karaoke. Quite deep bass for the price, even deeper than the JBL Boombox 4 in direct comparisons.
Cons: Unlike some other Zealot models, app-based EQ customization doesn’t appear to be fully supported yet, and IPX5 means it can handle splashes but not submersion.
