Short answer: it depends on the room, since these solve different problems. The Onn Large Party gen 2 packs wheels, a handle, FM radio and mic/guitar karaoke inputs with echo into a manageable 20.9 lbs (9.5 kg) cabinet, with independent testing confirming real bass impact for a large room, though Consumer Reports found boomy bass, hazy mids and smeared treble with no app or EQ to fix it. The Xiaomi Sound Party is IP67 rated for genuine dust and water protection at just 2.6 lbs (1.2 kg) with a claimed 26-hour battery and a warm, generally balanced sound when Bass Boost is off, though tested output tops out around 94dB and there is no aux input.
