Short answer: the JBL Partybox 110 for better sound quality, the Zealot PT21 for the lower price. The JBL Partybox 110 ranks #7 of 46 party speakers at $299.95. The Zealot PT21 ranks #12 at $216.73, $83.22 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 less than the Partybox 110. The catch: app-based EQ customization doesn’t appear to be fully supported yet.
On the JBL Partybox 110 side: Very neutral sound, slightly better than the Partybox 100. The tradeoff: bass isn’t as deep as that 100, 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 110 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.

JBL Partybox 110: $299.95 Amazon
Pros: Very neutral sound, slightly better than the Partybox 100.
Cons: Bass isn’t as deep as the Partybox 100. Just as loud and slightly deeper than a Stormbox Blast which is way smaller with better sound. Increase treble one step in the app to make it more neutral. Note, JBL daisychain is not compatible with any other non-JBL speaker and is possibly a fully digital signal.
