Partybox Stage 320 rates much higher and keeps more bass at volume, but costs over four times as much as the Onn Large Party gen 2. They rank 19 of 51 and 2 of 51.
Stage 320 has a removable battery, app EQ and customizable lighting, keeping more bass at high volume than the smaller 310, though it’s slightly sibilant in the treble at full blast and weighs a substantial 16.5kg.
Onn Large Party gen 2 is far cheaper and lighter with its own karaoke mic/guitar inputs and wheels, though Consumer Reports found its bass boomy and treble smeared with no app or EQ to fix it.
Buy the JBL Partybox Stage 320 if budget allows and you want app-controllable sound with a removable battery. Buy the Onn Large Party gen 2 if price is the priority and you still want karaoke inputs and wheels.
If battery life is a priority, the JBL Partybox Stage 320 is rated for 18 hours versus 12 hours for the Onn Large Party gen 2.

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.
