Onn Large Party gen 2 costs far less than the discontinued Sony GTK-XB72 and has comparably uneven tuning per our notes. They rank 19 of 51 and 48 of 51.
GTK-XB72 adds ClearAudio+ processing and a LIVE SOUND 3D mode with FM radio and app control, but our notes describe no deep bass at all, a weird midrange peak and rolled-off treble, and Sony has discontinued it.
Onn Large Party gen 2 has its own karaoke mic/guitar inputs, FM radio and wheels for far less money, though Consumer Reports found its own bass boomy and treble smeared.
Buy the Onn Large Party gen 2 over the discontinued Sony GTK-XB72: it costs far less with a similarly uneven tonal balance either way.
Skip the Sony GTK-XB72 if sound quality matters to you. It ranks near the bottom of the 51 party speakers.
If battery life is a priority, the Sony GTK-XB72 is rated for 23 hours versus 12 hours for the Onn Large Party gen 2.
If water resistance matters to you, the Onn Large Party gen 2 at IPX4 (splashing) holds up far better than the Sony GTK-XB72 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.
