These sit in different size classes, so this is not a straight ranking comparison. The Zealot PT21 ranks #12 of 46 party speakers by sound quality at $216.73; the Zealot ZE21 ranks #15 of 70 boombox speakers by sound quality at $187.15.
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. The catch: app-based EQ customization doesn’t appear to be fully supported yet.
On the Zealot ZE21 side: Great value for bass, playtime, and max volume in the boombox class, though the newer ZE41 now beats it. The tradeoff: a little rolled off up top, with bloated, muddy bass EQ.
Buy the Zealot PT21 at $216.73 if you want a party speaker. Buy the Zealot ZE21 at $187.15 if you want a boombox speaker instead.

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.

Zealot ZE21: $187.15 Aliexpress Amazon
Pros: Great value for the bass performance, play time and max volume in the boombox class, though the Zealot ZE41 now beats it out.
Cons: 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
