Samsung MX-ST50B adds app EQ and Group Play linking, but drops to a fraction of its power on battery and costs over double the Onn Large Party gen 2. They rank 19 of 51 and 25 of 51.
MX-ST50B’s 240W output and app EQ deliver clear, punchy sound on mains power with Group Play linking up to 10 speakers, but output drops sharply to 90W on battery and it lacks TWS stereo pairing.
Onn Large Party gen 2 costs much less with karaoke mic/guitar inputs and wheels of its own, though Consumer Reports found its bass boomy and treble smeared with no app or EQ.
Buy the Samsung MX-ST50B if app EQ and Group Play matter and you’ll mostly use it plugged into mains. Buy the Onn Large Party gen 2 for the lower price and simpler karaoke setup.
There is a real battery-life gap here: the Samsung MX-ST50B is rated for 18 hours, the Onn Large Party gen 2 only 12 hours.

The Two Speakers In Full
Onn Large Party gen 2: $129 Walmart eBay
Pros: A remarkably full-featured, manageable 9.5kg party speaker: wheels and handle, FM radio, aux, USB-A charging, mic and guitar inputs with karaoke echo, and Party Sync. Independent testing confirms bass with real impact and enough output for a large room; it is a clear improvement over the Gen 1 for low-end weight.
Cons: The low price shows in the refinement. Consumer Reports found boomy bass, hazy/grainy mids, a prominent smeared treble and a narrow, two-dimensional soundfield; it also notes distortion or other audio issues. There is no app or EQ to tame the tuning, and IPX4 only covers splashes rather than rain or immersion.

Samsung MX-ST50B: $300 Amazon eBay
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.
