Short answer: the Xdobo Wow Max. It ranks #21 of 113 boombox speakers by sound quality, rated 3.9/5, at $206.09; the W-King X20 ranks #43, rated 3.5/5, and costs $229.99, 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.
