Short answer: the Onn XL Wireless Party Speaker. It ranks #11 of 46 party speakers by sound quality, rated 4.1/5, at $249. The W-King T9 Pro ranks #32, rated 3.0/5, at $171.49, $77.51 cheaper, which does not close the gap in sound quality.
The Onn XL Wireless Party Speaker is the better-sounding, longer-running option. 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 is rated for 16 hours of battery against 12 for the W-King T9 Pro. It is rated IPX4, while the W-King T9 Pro has no water resistance. It has an adjustable EQ, which the W-King T9 Pro lacks. Watch for: Sound favors punch and a forward/bright top end over refinement.
The W-King T9 Pro is the lighter pick. A feature-rich rolling party speaker with dual 6.5-inch woofers, removable battery, TWS pairing, bass presets and music-synced lighting. At 20 lbs (9.05 kg) it weighs much less than the Onn XL Wireless Party Speaker at 44 lbs (19.96 kg). Watch for: Reviewer comparisons describe the tuning as warm and gritty rather than clean or detailed.
Buy the Onn XL Wireless Party Speaker. It is rated higher for sound quality, and the $77.51 saving on the W-King T9 Pro is not enough to make up the difference.

The Two Speakers In Full
Onn XL Wireless Party Speaker: $249.00 Walmart $249.00 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.

W-King T9 Pro: $171.49 AliExpress $171.49 eBay
Pros: A feature-rich rolling party speaker with dual 6.5-inch woofers, removable battery, TWS pairing, bass presets and music-synced lighting. The swappable battery is especially useful for long events, and its strong output gives it much more headroom than compact Bluetooth speakers.
Cons: Reviewer comparisons describe the tuning as warm and gritty rather than clean or detailed. Its claimed output figures should not be mistaken for neutral sound quality, and a large cabinet with no stated water rating is a poor fit for wet outdoor use.
