Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Partybox Stage 320 ranks #3 of 53 party speakers by sound quality at $569.95; the Zealot ZE41 ranks #17 of 113 boombox speakers by sound quality at $219.95.
Different sizes. The Stage 320 is a 36.4 lbs (16.5 kg) party speaker on wheels. The Zealot ZE41 is an 25.4 lbs (11.5 kg) boombox, one of the biggest and heaviest in its class. Each is rated within its own class.
The ZE41 is about value. It is the best value in the boombox class for bass, playtime and volume, but it is rolled off up top, not very balanced, and its bass EQ sounds bloated. Its claimed battery is only 4 hours, though its power bank, aux, mic input and USB playback make it flexible.
The Stage 320 is more refined and keeps more bass at high volume than the PartyBox 310. It has wheels, a removable battery with a claimed 18 hours, guitar and mic inputs, Auracast, lights and a 5-band app EQ.
Buy the JBL Partybox Stage 320 at $569.95 for a party speaker, or the Zealot ZE41 at $219.95 for a boombox speaker instead.
