Short answer: the Sony ULT Tower 7. It ranks #1 of 54 party speakers by sound quality (rated 4.7/5) at $648 and is still sold new; the Onn Large Party gen 1 ranks #41 (rated 2.7/5) and is discontinued, so it is only an option used. The Onn Large Party gen 1’s replacement, the Onn Large Party gen 2, is rated 3.9/5 at $129.
The Sony ULT Tower 7 is the better-sounding, longer-running pick. A big, loud party speaker on wheels with punchy bass, a 30 hour battery, 360 degree sound and inputs for mics and instruments. It is rated for 30 hours of battery against 13 for the Onn Large Party gen 1. It is rated IPX4, while the Onn Large Party gen 1 has no water resistance. It supports LDAC Bluetooth, which the Onn Large Party gen 1 lacks. The tradeoff: 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.
The Onn Large Party gen 1 is the lighter option. A rolling party speaker with FM radio, a mic and guitar input, lights, and phone charging for casual outdoor parties. At 23.1 lbs (10.5 kg) it weighs much less than the Sony ULT Tower 7 at 50.3 lbs (22.8 kg). The catch: Sound is not a strong reason to seek one out.
Buy the Sony ULT Tower 7. It is rated higher for sound quality, and the Onn Large Party gen 1 is discontinued, so it is only available used.
