These are not really the same size class, and that is the honest framing here. The JBL Partybox 110 ranks #9 of 40 party speakers by sound quality at $379.95; the Zealot ZE51 ranks #16 of 76 boombox speakers by sound quality at $296.39.
Why pick the JBL Partybox 110: Very neutral sound, slightly better than the Partybox 100. Watch for: Bass isn’t as deep as the Partybox 100.
What the Zealot ZE51 does well: Cleaner sound and a wider stereo soundstage than the Zealot ZE41, with less distortion at high volume for better instrumental detail and clarity. The tradeoff: The Zealot ZE41 still wins on raw bass depth and price.
Buy the JBL Partybox 110 ($379.95) for a party speaker; the Zealot ZE51 ($296.39) suits a boombox speaker instead.
If battery life is a priority, the JBL Partybox 110 is rated for 12 hours versus 4 hours for the Zealot ZE51.

Newer model: the JBL Partybox Club 120, rated 4.5/5.
Pros: Very neutral sound, slightly better than the Partybox 100. Measured bass extension of 41Hz (-10dB).
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.

Zealot ZE51: $296.39 after coupon Amazon AliExpress eBay
Pros: Cleaner sound and a wider stereo soundstage than the Zealot ZE41, with less distortion at high volume for better instrumental detail and clarity.
Cons: The Zealot ZE41 still wins on raw bass depth and price. Large and heavy like the rest of the boombox class, and clarity still isn’t up to dedicated hi-fi speakers.
