These sit in different size classes, so this is not a straight ranking comparison. The Google Nest Mini 2nd Gen ranks #8 of 9 powered desktop speakers by sound quality at $109.95; the JBL Authentics 300 ranks #32 of 75 boombox speakers by sound quality at $299.95.
The case for the Google Nest Mini 2nd Gen: Digital Trends’ review found it responds quickly, automatically raises music and response volume over background noise, and is built from recycled plastic. The tradeoff: Digital Trends’ main complaint was that maximum volume could be louder, and RTINGS’ independent review agrees, naming it their one real weakness.
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 Google Nest Mini 2nd Gen at $109.95 for a powered desktop speaker, or the JBL Authentics 300 at $299.95 for a boombox speaker instead.
Skip the Google Nest Mini 2nd Gen if sound quality matters to you. It ranks near the bottom of the 9 powered desktop speakers.

The Two Speakers In Full
Google Nest Mini 2nd Gen: $109.95 each Discontinued Amazon eBay
Pros: Digital Trends’ review found it responds quickly, automatically raises music and response volume over background noise, and is built from recycled plastic. Its 40mm driver is clearer through the midrange and treble than the larger-driver Amazon Echo Dot 3rd Gen it was tested against, though the Echo had more bass and outright volume. A physical microphone mute switch is on the side.
Cons: Digital Trends’ main complaint was that maximum volume could be louder, and RTINGS’ independent review agrees, naming it their one real weakness. There is no 3.5mm or other wired audio input of any kind. This model has been discontinued by Google in favor of the newer Google Home Speaker, so current retail listings run well above the original $49 launch price as remaining stock sells through resellers. Discontinued.
