Short answer: the Sony ULT Tower 7 on measured sound quality, the Onn Large Party gen 2 on price. The Sony ULT Tower 7 ranks #1 of 39 party speakers at $648. The Onn Large Party gen 2 ranks #15 at $129, $519 cheaper.
What the Onn Large Party gen 2 offers: 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. Watch for: 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.
What the Sony ULT Tower 7 offers: A compelling large-party value at $649.99: 420W output, an IPX4-rated 30-hour battery, 360-degree sound, wheels and four carry handles at 22.8kg. The full review praises its punchy, clean ULT1 bass, ULT2’s higher-output mode, simplified controls and unusually complete I/O: USB-C, USB-A, RCA, balanced XLR and mic input. Watch for: The reviewer notes that Auracast pairing is not backward-compatible with Sony’s older Party Connect speakers, and the hard-plastic corners lack protective rubber bumpers. IPX4 is splash resistance rather than full weatherproofing; the 30-hour claim requires lights off.
Buy the Onn Large Party gen 2 when the price outweighs sound quality for you, and the Sony ULT Tower 7 when sound quality outweighs the price instead.
There is a real battery-life gap here: the Sony ULT Tower 7 is rated for 30 hours, the Onn Large Party gen 2 only 12 hours.
