Short answer: the Zealot S97. It ranks #49 of 82 large speakers by sound quality, rated 3.4/5, at $65.86; the Doss Extreme Boom ranks #80, rated 2.1/5, and costs $79.99, which makes this an easy call rather than a real tradeoff.
Why pick the Zealot S97: For a compact 3.3kg boombox, the S97 delivers unusually deep, clean-enough bass with a more sensible default balance than many inexpensive Zealot models. Watch for: It is not especially loud for its size, battery life is only a claimed 12 hours, and the bass preset can swamp the rest of the music.
The case for the Doss Extreme Boom: A durable 2.52kg outdoor speaker with claimed 60W output, IPX7 protection, USB-C charging, aux and microSD playback, speakerphone capability, a power bank and TWS pairing. Watch for: The measured 65Hz -10dB bass point means it lacks true low bass despite its boomy voicing.
Buy the Zealot S97. It is rated higher for sound quality than the Doss Extreme Boom and costs less, so only choose the other one for a particular feature it does better.
Battery life favors the Doss Extreme Boom: rated for 30 hours against 12 hours for the Zealot S97.

Zealot S97: $65.86 with coupon YZZL10 AliExpress eBay
Pros: For a compact 3.3kg boombox, the S97 delivers unusually deep, clean-enough bass with a more sensible default balance than many inexpensive Zealot models. It also brings IPX6 protection, aux and microSD playback, power-bank outputs, three EQ presets and PartyAdd linking.
Cons: It is not especially loud for its size, battery life is only a claimed 12 hours, and the bass preset can swamp the rest of the music. There is no app or fine-grained EQ, so the Vocal preset is the only practical way to improve the balance. It is still heavy for a speaker with this output ceiling.

Doss Extreme Boom: $79.99 Amazon eBay
Pros: A durable 2.52kg outdoor speaker with claimed 60W output, IPX7 protection, USB-C charging, aux and microSD playback, speakerphone capability, a power bank and TWS pairing. It offers long claimed battery life and can play loudly enough for a casual party, with a bass-heavy sound that carries outdoors. Measured bass extension of 65Hz (-10dB).
Cons: The measured 65Hz -10dB bass point means it lacks true low bass despite its boomy voicing. Reviews describe fuzzy mids, mushy bass when pushed and rolled-off treble, while there is no app or EQ to restore balance. It is best for loud background music, not clear or refined listening.
