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. The JBL Partybox Encore is discontinued; its replacement is the JBL Partybox Encore 2. If you are buying new, get the JBL Partybox Encore 2.
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.
