Onn XL Wireless Party Speaker vs Samsung MX-ST50B

Last updated: October 13, 2026

Short answer: the Onn XL Wireless Party Speaker. It ranks #11 of 46 party speakers by sound quality (rated 4.1/5) at $249 and is still sold new; the Samsung MX-ST50B ranks #25 (rated 3.6/5) and is discontinued, so it is only an option used.

Onn XL Wireless Party Speaker vs Samsung MX-ST50B

The Onn XL Wireless Party Speaker is the better-sounding pick. 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.

The Samsung MX-ST50B is the lighter choice. A 240W sound tower with two 6.5-inch woofers and two tweeters, IPX5 protection, app EQ, aux and USB playback, karaoke input and Samsung Group Play for linking up to 10 speakers. At 26.2 lbs (11.9 kg) it weighs much less than the Onn XL Wireless Party Speaker at 44 lbs (19.96 kg). Watch for: Output drops sharply to 90W on battery, so it needs mains power for its full impact.

Buy the Onn XL Wireless Party Speaker. It is rated higher for sound quality; the Samsung MX-ST50B is no longer sold new.

Onn XL Wireless Party Speaker ranking card

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.

Samsung MX-ST50B: $300 Discontinued Amazon $300 eBay

Samsung MX-ST50B ranking card

Pros: A 240W sound tower with two 6.5-inch woofers and two tweeters, IPX5 protection, app EQ, aux and USB playback, karaoke input and Samsung Group Play for linking up to 10 speakers. Hands-on reviews find it capable of clear, punchy sound and impressive output for indoor parties, while its 18-hour claimed battery supports more casual use away from mains power.

Cons: Output drops sharply to 90W on battery, so it needs mains power for its full impact. Bass is not as deep as stronger dedicated party speakers, and at 11.9kg its tall enclosure is less convenient to carry. It lacks TWS stereo pairing, so the Group Play feature favors shared party coverage rather than a conventional stereo image. Discontinued.
