#11 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.

How it compares: Just above it: JBL Partybox 300 - $51 more, 2 more hours of battery life. Just below it: Zealot PT21 - $23 cheaper, 44 more hours of battery life.
