Hopestar A90 vs JBL Authentics 300

Last updated: September 30, 2026

Short answer: the Hopestar A90. It ranks #22 of 89 boombox speakers by sound quality, rated 3.9/5, at $351.65. The JBL Authentics 300 ranks #40, rated 3.5/5, at $299.95, $51.70 cheaper, not enough of a saving to outweigh the sound-quality gap.

Hopestar A90 vs JBL Authentics 300

The case for the Hopestar A90: A huge, powerful 700W boombox with eight drivers (two 5” woofers, two 3.5” midranges and four tweeters), a removable 36,000mAh battery and a wireless microphone. The catch: The JBL PartyBox Encore Essential 2 was the better, more refined listen in a direct comparison.

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.

Buy the Hopestar A90. It is rated higher for sound quality, and the $51.70 saving on the JBL Authentics 300 is not enough to make up the difference.

If water resistance matters to you, the Hopestar A90 at IPX6 (powerful water jets) holds up far better than the JBL Authentics 300 at no water resistance.

Hopestar A90 ranking card

Pros: A huge, powerful 700W boombox with eight drivers (two 5” woofers, two 3.5” midranges and four tweeters), a removable 36,000mAh battery and a wireless microphone. In side by side tests it had better highs, clarity and soundstage than the Zealot ZE21 while still reaching deep, reviewers picked it over the JBL Boombox 4 for its bass and output, and it sounded powerful and true to the music against the JBL PartyBox Encore Essential 2. Bluetooth 5.4 with Auracast, IPX6, USB, TF and aux inputs, RGB lights and a strap attachment.

Cons: The JBL PartyBox Encore Essential 2 was the better, more refined listen in a direct comparison. The Yeahbox Sonic Boom Ultra measured roughly 3 to 5dB louder. There is no app or EQ. It is very large and heavy (13.2 kg boxed), claims only 6 to 8 hours of battery, and it is sold through AliExpress rather than US retailers.
