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 51 party speakers, rated 4.7/5, at $548. The Onn Large Party gen 2 ranks #17, rated 3.9/5, at $129, $419 cheaper.
The Onn Large Party gen 2 is the lighter pick. A budget party speaker on wheels with real bass impact, karaoke inputs and an FM radio. At 20.9 lbs (9.5 kg) it weighs much less than the Sony ULT Tower 7 at 50.3 lbs (22.8 kg). The catch: The low price shows in the refinement.
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 12 for the Onn Large Party gen 2. It supports LDAC Bluetooth, which the Onn Large Party gen 2 lacks. It has an adjustable EQ, which the Onn Large Party gen 2 lacks. The catch: 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.
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.
