Short answer: the JBL Authentics 300 if sound quality matters most, the Havit BassBlast Go if price matters most. The JBL Authentics 300 ranks #40 of 89 boombox speakers, rated 3.5/5, at $299.95. The Havit BassBlast Go ranks #47, rated 3.4/5, at $77.99, $221.96 cheaper.
Why pick the JBL Authentics 300: Integrates both Amazon Alexa and Google Assistant simultaneously (rare for smart speakers). The catch: Narrow sounding, bass not as deep as others.
Why pick the Havit BassBlast Go: Jagist found it a strong value for a medium size boombox, with a lot of bass for its size and a good balance on the Rock EQ. The catch: In the only side by side against a rated speaker, listeners preferred the W-King H330, and Techder Audios found the Tribit Stormbox Lava clearly better in sound and build.
Buy the JBL Authentics 300 if sound quality matters more than the price. Buy the Havit BassBlast Go if the price matters more than sound quality.
There is a real gap in water resistance: the Havit BassBlast Go at IPX6 (powerful water jets) against the JBL Authentics 300, which has no water resistance.

Havit BassBlast Go: $77.99 Amazon eBay
Pros: Jagist found it a strong value for a medium size boombox, with a lot of bass for its size and a good balance on the Rock EQ. Two woofers and two tweeters give true stereo from one unit, and it adds IPX6 water resistance, Bluetooth 5.3, the Havit Life app with 8 EQ presets, a 6.35mm microphone input with echo control, aux and USB playback, a small status screen, RGB lights, stereo pairing and a power bank output.
Cons: In the only side by side against a rated speaker, listeners preferred the W-King H330, and Techder Audios found the Tribit Stormbox Lava clearly better in sound and build. Vocals are weaker than rivals’, and owners report the battery drains far faster than its 12 hour rating. The evidence is thin: one comparison and a handful of listening reviews.
