These are not really the same size class, and that is the honest framing here. The Onn Large Party gen 2 ranks #16 of 40 party speakers by sound quality at $129; the JBL Partybox On the Go ranks #47 of 76 boombox speakers by sound quality at $300.
The case for the Onn Large Party gen 2: 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. The catch: The low price shows in the refinement.
What the JBL Partybox On the Go does well: JBL Partybox On the Go uses 5.1” woofer + tweeters. The catch: Bass is limited by its 49Hz specification.
Buy the Onn Large Party gen 2 at $129 if you want a party speaker. Buy the JBL Partybox On the Go at $300 if you want a boombox speaker instead.
There is a real battery-life gap here: the Onn Large Party gen 2 is rated for 12 hours, the JBL Partybox On the Go only 6 hours.

The Two Speakers In Full
Onn Large Party gen 2: $129 Walmart eBay
Older model: the Onn Large Party gen 1 (rated 2.7/5).
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.

JBL Partybox On the Go: $300 Amazon eBay
Newer model: the JBL PartyBox On-The-Go 2 Plus, rated 4.4/5.
Pros: JBL Partybox On the Go uses 5.1” woofer + tweeters. Its 7.5 kg, claimed 6 hours (Manufacturer specified) battery life, IPX4 protection, aux input, up to 94dB and limited-stereo playback make it a practical option for its intended room or portable use. A wireless microphone is included. Measured bass extension of 49Hz (-10dB).
Cons: Bass is limited by its 49Hz specification. No EQ adjustment. Battery life is short, and its sound trails the rest of the Partybox line.
