Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Partybox 130 ranks #7 of 40 party speakers by sound quality at $449.95; the Zealot ZE51 ranks #16 of 76 boombox speakers by sound quality at $296.39.
Why pick the JBL Partybox 130: A relatively manageable 11.3kg PartyBox with removable battery, foldable handle, light show, USB audio and modern JBL connectivity. Watch for: It is still bass-forward and less clear than the PartyBox 120 in direct comparisons.
Why pick the Zealot ZE51: 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 130 at $449.95 for a party speaker, or the Zealot ZE51 at $296.39 for a boombox speaker instead.

The Two Speakers In Full
JBL Partybox 130: $449.95 Amazon eBay
Pros: A relatively manageable 11.3kg PartyBox with removable battery, foldable handle, light show, USB audio and modern JBL connectivity. Independent reviews describe it as unusually balanced and powerful for its format, while owner feedback praises clear voices and deep bass.
Cons: It is still bass-forward and less clear than the PartyBox 120 in direct comparisons. The smaller battery and stripped-back controls/features make it a questionable upgrade when the 120 is similarly priced. JBL’s wired daisy chain only works with other JBL speakers.

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.
