Short answer: the W-King D20 if the bundled microphones matter, since the Yeahbox’s specs are manufacturer-claimed. The D20 includes two wireless microphones, but its frequency response rises with the upper treble rolled off and peaks at 700Hz and 1.2kHz. The Sonic Boom Max 3 lists 200W RMS (300W peak) in a true 3-way, 5-driver array, yet it is a budget brand with limited independent testing.
On the W-King D20 side: Comes with 2 wireless microphones. Set against that: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
The case for the Yeahbox Sonic Boom Max 3: 200W RMS (300W peak) true 3-way, 5-driver array. Set against that: A budget import brand with limited independent testing - specs are manufacturer-claimed.
Buy the W-King D20. It ranks higher for sound quality than the Yeahbox Sonic Boom Max 3 and costs less, so the other one has nothing left to offer.

Yeahbox Sonic Boom Max 3: $228.99 Amazon eBay
Pros: A large 3-way, 5-driver party speaker with claimed 200W RMS output, a 111Wh battery, USB-C fast charging, app EQ, TWS pairing, and aux, USB and microSD playback. Listener comparisons describe powerful bass, strong output and decent mids and highs for outdoor party use.
Cons: There is limited independent testing and the water/dust rating is reported inconsistently across listings. Listener comparisons find it less clear and refined than stronger boombox rivals, so its big bass and output are a better fit for parties than critical listening.
