Neither of these excels at sound quality, but Hyperboom costs over three times as much for what our own notes call dull and muddy sound. They rank 19 of 51 and 32 of 51.
Hyperboom pairs dual 4.5” woofers and tweeters with adaptive bass compensation and dual Bluetooth pairing for a 24-hour battery, but our notes describe it as expensive for what it does, with dull, muddy sound and less bass than the JBL Partybox 100.
Onn Large Party gen 2 costs far less with karaoke mic/guitar inputs and wheels of its own, though Consumer Reports found its own bass boomy and treble smeared.
Buy the Onn Large Party gen 2 for the much lower price and more party-oriented features like karaoke inputs and wheels. Buy the Ultimate Ears Hyperboom only if its compact square design and dual-device pairing specifically appeal to you.
There is a real battery-life gap here: the Ultimate Ears Hyperboom is rated for 24 hours, the Onn Large Party gen 2 only 12 hours.
If water resistance matters to you, the Onn Large Party gen 2 at IPX4 (splashing) holds up far better than the Ultimate Ears Hyperboom at no water resistance.

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.
