Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Zealot ZE41 ranks #17 of 113 boombox speakers by sound quality at $219.95; the Onn Large Party gen 2 ranks #17 of 53 party speakers by sound quality at $129.
What the Zealot ZE41 does well: A huge boombox with lots of bass, volume and play time for the money. It has an adjustable EQ, which the Onn Large Party gen 2 lacks. The tradeoff: The heaviest and biggest boombox speaker around.
The Onn Large Party gen 2 is the longer-running choice. A budget party speaker on wheels with real bass impact, karaoke inputs and an FM radio. It is rated for 12 hours of battery against 4 for the Zealot ZE41. Watch for: The low price shows in the refinement.
Buy the Zealot ZE41 ($219.95) for a boombox speaker; the Onn Large Party gen 2 ($129) suits a party speaker instead.
