Short answer: the Zealot ZE41. It ranks #17 of 112 boombox speakers by sound quality, rated 4.1/5, at $219.95. The Onn Medium Party Speaker Gen 2 ranks #65, rated 3.1/5, at $90, $129.95 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Zealot ZE41 is the better-sounding option. A huge boombox with lots of bass, volume and play time for the money. It has an adjustable EQ, which the Onn Medium Party Speaker Gen 2 lacks. It plays in stereo from a single unit, unlike the Onn Medium Party Speaker Gen 2. The tradeoff: The heaviest and biggest boombox speaker around.
The Onn Medium Party Speaker Gen 2 is the longer-running, lighter pick. An affordable waterproof party speaker with a big woofer, lights, a karaoke mic input and FM radio. It is rated for 20 hours of battery against 4 for the Zealot ZE41. At 11 lbs (5 kg) it weighs much less than the Zealot ZE41 at 25.3 lbs (11.48 kg). It is rated IPX7 against IPX5 for the Zealot ZE41. The tradeoff: Lacking detail compared to the Onn Large Party gen 2 and not as deep of bass.
Buy the Zealot ZE41. It is rated higher for sound quality, and the $129.95 saving on the Onn Medium Party Speaker Gen 2 is not enough to make up the difference.
