Short answer: the Zealot S95. It ranks #37 of 112 boombox speakers by sound quality, rated 3.7/5, at $157.41. The Onn Medium Party Speaker Gen 2 ranks #65, rated 3.1/5, at $90, $67.41 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Onn Medium Party Speaker Gen 2 is the longer-running 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 12 for the Zealot S95. The tradeoff: Lacking detail compared to the Onn Large Party gen 2 and not as deep of bass.
The Zealot S95 is the better-sounding option. An affordable stereo boombox with water resistance, a power bank output and linking for up to 100 speakers. 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: A little rolled off up top and not that balanced through the rest of the range.
Buy the Zealot S95. It is rated higher for sound quality, and the $67.41 you would save on the Onn Medium Party Speaker Gen 2 does not close the gap.
