Short answer: the Bugani Brief Pro. It ranks #28 of 91 boombox speakers by sound quality, rated 3.8/5, at $99.98; the JBL Authentics 300 ranks #41, rated 3.5/5, and costs $299.95, which makes this an easy call rather than a real tradeoff.
The Bugani Brief Pro is the longer-running option. 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 is rated for 12 hours of battery against 8 for the JBL Authentics 300. 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 case for the JBL Authentics 300: Integrates both Amazon Alexa and Google Assistant simultaneously (rare for smart speakers). The tradeoff: Narrow sounding, bass not as deep as others.
Buy the Bugani Brief Pro. It is rated higher for sound quality than the JBL Authentics 300 and costs less, so only choose the other one for a particular feature it 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.
