Short answer: the Zealot PT21. Both are rated 4.1/5 for sound quality (#12 and #11 of 49 party speakers), and the Zealot PT21 costs $225.86 against $249 for the Onn XL Wireless Party Speaker, so with nothing between them on sound quality, price settles it.
Why pick the Onn XL Wireless Party Speaker: 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 tradeoff: Sound favors punch and a forward/bright top end over refinement.
The Zealot PT21 is the longer-running, lighter choice. Dual 166mm woofers and 200W output in a lighter, more compact body than the Zealot ZE41, with a bundled wireless microphone and echo effect built in for karaoke. It is rated for 60 hours of battery against 16 for the Onn XL Wireless Party Speaker. At 20.7 lbs (9.4 kg) it weighs much less than the Onn XL Wireless Party Speaker at 44 lbs (19.96 kg). The tradeoff: Unlike some other Zealot models, app-based EQ customization doesn’t appear to be fully supported yet, and IPX5 means it can handle splashes but not submersion.
