Zealot ZE01 vs JBL Authentics 300

Last updated: August 18, 2026

Short answer: the Zealot ZE01. It ranks #25 of 73 boombox speakers by sound quality at $126.02; the JBL Authentics 300 ranks #30 and costs $299.95, so there is not much of a tradeoff to weigh.

On the Zealot ZE01 side: Appears to be the same internals as the S95. Set against that: A little rolled off up top and not that balanced through the rest of the range.

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 Zealot ZE01. It ranks higher for sound quality than the JBL Authentics 300 and costs less, so there is no real case for the other one.

If battery life is a priority, the Zealot ZE01 is rated for 40 hours versus 8 hours for the JBL Authentics 300.

If water resistance matters to you, the Zealot ZE01 at IPX6 (powerful water jets) holds up far better than the JBL Authentics 300 at no water resistance.
