Short answer: the Bugani Brief Pro. Both are rated 3.8/5 for sound quality (#28 and #27 of 91 boombox speakers), and the Bugani Brief Pro costs $99.98 against $349.95 for the JBL Boombox 3, so with nothing between them on sound quality, price settles it.
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 JBL Boombox 3 is the longer-running pick. 24 hour battery life (6.5 hour charge time). It is rated for 24 hours of battery against 12 for the Bugani Brief Pro. The tradeoff: Dips in mid bass range which makes the bass sound undefined, bass boosted, peaky at 700Hz, not quite as good mids and treble as the Blast.
Buy the Bugani Brief Pro. Both are rated the same for sound quality, and it costs $249.97 less than the JBL Boombox 3.

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.
