Short answer: the Bugani Brief Pro. It ranks #28 of 91 boombox speakers by sound quality, rated 3.8/5, at $99.98; the W-King X20 ranks #38, rated 3.5/5, and costs $219.98, so there is little reason to consider the other one.
Why pick the Bugani Brief Pro: Crystal clear and detailed with good separation of instruments and vocals, impressive for a two-way layout of two 4” woofers and two 44mm tweeters on 80W RMS. Watch for: It turns a little harsh and fatiguing at 80% to 100% volume while losing bass, and it doesn’t reach as deep as the Go + Play 3, which reviewers still preferred for its thicker, richer bass.
The W-King X20 is the longer-running pick. It is rated for 24 hours of battery against 12 for the Bugani Brief Pro. Watch for: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
Buy the Bugani Brief Pro. It is rated higher for sound quality than the W-King X20 and costs less, which makes it the one to get unless you need something the other one does better.

The Two Speakers In Full
Bugani Brief Pro: $99.98 Amazon eBay
Pros: Crystal clear and detailed with good separation of instruments and vocals, impressive for a two-way layout of two 4” woofers and two 44mm tweeters on 80W RMS. It plays louder than the Harman Kardon Go + Play 3 and, in side by side sound tests, many listeners preferred it to the JBL Xtreme 4 and found it close to the EarFun UBoom X. A claimed 12 hours of battery, Bluetooth 5.3 and stereo pairing, at a low price.
Cons: It turns a little harsh and fatiguing at 80% to 100% volume while losing bass, and it doesn’t reach as deep as the Go + Play 3, which reviewers still preferred for its thicker, richer bass. No published water rating.
