Short answer: the Zealot ZE21 for output, the S95 if you want to spend less. The ZE21 is a great value for bass performance, play time and max volume in the boombox class, though the ZE41 now beats it and it is a little rolled off up top. The S95 is the cheaper buy at $157.41 and a good value in its own right, with the same rolled-off, less-than-balanced character.
Buy the Zealot ZE21. It is rated higher for sound quality, and saving $90 with the Zealot S95 does not make up for the sound-quality gap.

The Two Speakers In Full
Zealot ZE21: $247.41 Amazon AliExpress eBay
Pros: The ZE21’s main attraction is unusually deep bass for a battery boombox: owner testing finds real output in the 40-50Hz region and audibility down toward the low 30s. Its TWS button can form a stereo pair with another compatible Zealot, and its large, rugged chassis gives it credible party-speaker scale. Measured bass extension of 36Hz (-10dB).
Cons: That deep-bass emphasis comes with a pronounced 60-110Hz kick-bass dip and over-loud 250-600Hz lower mids, which can make rock and pop sound hollow or boxy. The supplied sound modes do not fully correct the tuning; the most positive independent report required source-side parametric EQ. Treble is also soft and clarity trails better-tuned rivals.

Zealot S95: $157.41 Amazon AliExpress eBay
Pros: A good value for the boombox class. Appears to be the same internals as the ZE01. Bigger case and goes deeper than the ZE01. Measured bass extension of 45Hz (-10dB).
Cons: A little rolled off up top and not that balanced through the rest of the range. Clarity isn’t as good as better speakers.
