Short answer: the Zealot ZE51. It ranks #16 of 91 boombox speakers by sound quality, rated 4.1/5, at $296.39. The XDOBO Wow Max ranks #21, rated 3.9/5, at $206.09, $90.30 cheaper, a saving that is not big enough to make up the sound-quality gap.
What the Zealot ZE51 does well: Cleaner sound and a wider stereo soundstage than the Zealot ZE41, with less distortion at high volume for better instrumental detail and clarity. The tradeoff: The Zealot ZE41 still wins on raw bass depth and price.
The XDOBO Wow Max is the longer-running, lighter pick. Big, loud and bass-heavy, with an eight-driver, 300W layout and bass rated down to 32Hz. It is rated for 8 hours of battery against 4 for the Zealot ZE51. At 15.4 lbs (7 kg) it weighs much less than the Zealot ZE51 at 26 lbs (11.81 kg). Watch for: At low and mid volume the JBL Boombox 4 sounds better in the mids and highs; the Wow Max comes across slightly muted and bass forward there, with its midrange not aimed at ear level.
Buy the Zealot ZE51. It is rated higher for sound quality, and the $90.30 you would save on the XDOBO Wow Max does not close the gap.

Zealot ZE51: $296.39 after coupon Amazon AliExpress eBay
Pros: Cleaner sound and a wider stereo soundstage than the Zealot ZE41, with less distortion at high volume for better instrumental detail and clarity.
Cons: The Zealot ZE41 still wins on raw bass depth and price. Large and heavy like the rest of the boombox class, and clarity still isn’t up to dedicated hi-fi speakers.

XDOBO Wow Max: $206.09 Amazon eBay
Pros: Big, loud and bass-heavy, with an eight-driver, 300W layout and bass rated down to 32Hz. In side by side tests it sounded better balanced and clearer than the Zealot ZE21, with smooth mids and punchy yet deep bass, handled high volume better than the JBL Boombox 4, which gets screechy and drops bass at max, and clearly beat the Sony ULT Field 7 and W-King X20. Two wireless microphones are included, and it charges over USB-C at up to 20V.
Cons: At low and mid volume the JBL Boombox 4 sounds better in the mids and highs; the Wow Max comes across slightly muted and bass forward there, with its midrange not aimed at ear level. About 7 kg, and only a claimed 8 hours of battery.
