Short answer: these are not really competing for the same buyer. The PT21 ranks #12 of 39 party speakers at $225.86. The ZE41 ranks #16 of 75 boombox speakers at $259.90. Both are strong values within their own class, so the real choice is which size and role you need.
The PT21 is the lighter, more portable option built around karaoke. It pairs dual 166mm woofers with a bundled wireless microphone that has an echo effect built in, and its own notes say it gets even deeper bass than the JBL Boombox 4 in direct comparisons. The catch is that app-based EQ customization does not appear to be fully supported yet, and at 20.7 lbs it is meaningfully lighter and more compact than the ZE41.
The ZE41 is the brand’s boombox-class flagship, built for maximum output. Its pros text calls it the best value in the boombox class for bass, playtime, and max volume, backed by a larger 191x130mm subwoofer and 300W of output against the PT21’s 200W. The tradeoff is size and tuning: it is the heaviest and biggest boombox around at 25.3 lbs, and its cons call out a bass EQ that runs bloated and muddy along with a top end that is a little rolled off.
Everything else matches: both share the same 48000mAh battery capacity, IPX5 rating, Bluetooth 5.3, PartyAdd multi-speaker pairing, USB-C charging, and karaoke-ready microphone input.
Buy the Zealot PT21 if you want a party speaker with karaoke built in and don’t need maximum output.
Buy the Zealot ZE41 if you specifically want a boombox-class flagship and can live with the extra size and weight.
If battery life is a priority, the Zealot PT21 is rated for 60 hours versus 4 hours for the Zealot ZE41.

The Two Speakers In Full
Zealot PT21: $216.73 Aliexpress eBay
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 ZE41: $259.90 Amazon Aliexpress eBay
Pros: The absolute best value for the bass performance, play time and max volume in the boombox class.
Cons: The heaviest and biggest boombox speaker around. 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.
