These are not really the same size class, and that is the honest framing here. The Onn XL Wireless Party Speaker ranks #11 of 40 party speakers by sound quality at $249; the Zealot ZE41 ranks #17 of 76 boombox speakers by sound quality at $259.90.
What the Onn XL Wireless Party Speaker does well: A compelling all-in-one party and karaoke package: dual 8-inch woofers, 240W claimed output, two included wireless microphones, dual mic/guitar inputs, karaoke effects and USB-A phone charging. The catch: Sound favors punch and a forward/bright top end over refinement.
What the Zealot ZE41 does well: 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 Onn XL Wireless Party Speaker ($249) for a party speaker; the Zealot ZE41 ($259.90) suits a boombox speaker instead.
There is a real battery-life gap here: the Onn XL Wireless Party Speaker is rated for 16 hours, the Zealot ZE41 only 4 hours.

The Two Speakers In Full
Onn XL Wireless Party Speaker: $249.00 Walmart eBay
Pros: A compelling all-in-one party and karaoke package: dual 8-inch woofers, 240W claimed output, two included wireless microphones, dual mic/guitar inputs, karaoke effects and USB-A phone charging. It plays loudly enough for backyard use and has punchy bass; owners especially like the wheels, telescoping handle and colorful light effects. At 44 lb it is still a substantial cabinet, but the trolley design makes moving it far easier than carrying it.
Cons: Sound favors punch and a forward/bright top end over refinement. Independent comparisons and owner reports find the bass less deep and the overall balance less satisfying than the JBL PartyBox 320; several consider the far-cheaper Onn Large Party gen 2 the better sound-per-dollar buy. Some owners report distortion or static at high volume, and a few report wireless-mic pairing/dropout problems. Large (30 inches tall, 44 lb) and only IPX4 splash-resistant, not a speaker to leave out in rain.

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.
