Short answer: the XDOBO Wow Max. It ranks #21 of 85 boombox speakers by sound quality, rated 3.9/5, at $206.09; the W-King X20 ranks #36, rated 3.5/5, and costs $219.98, so there is little reason to consider the other one.
The Wow Max came out ahead in a side by side test, with smooth mids and deep, punchy bass. The X20 has a rising frequency response with peaks around 700Hz and 1.2kHz, though it measured about 112dB and reaches about 42Hz.
Battery favors the X20: a claimed 24 hours with a power bank, against 8 for the Wow Max. The Wow Max includes two wireless microphones.
Evidence: the Wow Max’s rating comes from listening comparisons, not measurements.
Buy the XDOBO Wow Max. It is rated higher for sound quality than the W-King X20 and costs less, so only choose the other one for a particular feature it does better.

The Two Speakers In Full
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. The evidence is listening comparisons rather than measurements. About 7 kg, and only a claimed 8 hours of battery.
