Short answer: JBL Partybox Encore is the more compact, better-balanced party speaker, while Zealot ZE41 is the extreme bass, runtime, and output value proposition. Encore’s boosted-bass sound is engaging but its medium-volume battery life is short; ZE41 earns its output with a much bigger and heavier enclosure.
What the JBL Partybox Encore gets right: A great sounding somewhat boosted bass party speaker. The tradeoff: Only 10 hours of battery at medium volume.
On the Zealot ZE41 side: The absolute best value for the bass performance, play time and max volume in the boombox class. The catch: The heaviest and biggest boombox speaker around.
Buy the JBL Partybox Encore if you want a more manageable party speaker with a polished, lively sound.
Buy the Zealot ZE41 if maximum bass, play time, and output per dollar matter more than portability.

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.
