These sit in different size classes, so this is not a straight ranking comparison. The Google Home Speaker ranks #7 of 9 powered desktop speakers by sound quality at $99.99; the JBL Authentics 300 ranks #32 of 75 boombox speakers by sound quality at $299.95.
The case for the Google Home Speaker: Built-in Gemini support makes it a capable smart home hub, with a Thread border router and Matter support, and the compact 107mm sphere fits almost anywhere. The tradeoff: This is Google’s current speaker, and reviewers agree it is a downgrade in sound from the discontinued Nest Audio it replaces: SoundGuys measured its acoustic hardware directly against the Nest Audio and found a single 58mm full-range driver against the Nest Audio’s 75mm woofer plus dedicated 19mm tweeter, calling it ‘half the audio hardware for the same sticker price.’ In their listening test there was barely any bass, the sound turned thin and tinny outside the midrange, and pushing the volume up made high notes shrill.
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 Home Speaker ($99.99) for a powered desktop speaker; the JBL Authentics 300 ($299.95) suits a boombox speaker instead.
If sound quality matters at all to you, skip the Google Home Speaker. It ranks near the bottom of the 9 powered desktop speakers, so look higher up the list instead.

The Two Speakers In Full
Google Home Speaker: $99.99 each Amazon eBay
Pros: Built-in Gemini support makes it a capable smart home hub, with a Thread border router and Matter support, and the compact 107mm sphere fits almost anywhere. Vocals come through clearly on most tracks, which SoundGuys’ side-by-side listening called the one thing this speaker does well.
Cons: This is Google’s current speaker, and reviewers agree it is a downgrade in sound from the discontinued Nest Audio it replaces: SoundGuys measured its acoustic hardware directly against the Nest Audio and found a single 58mm full-range driver against the Nest Audio’s 75mm woofer plus dedicated 19mm tweeter, calling it ‘half the audio hardware for the same sticker price.’ In their listening test there was barely any bass, the sound turned thin and tinny outside the midrange, and pushing the volume up made high notes shrill. There is no aux input or any wired audio connection at all, the single USB-C port is power only, and Bluetooth is limited to the SBC codec with no AAC support. SoundGuys scored it 6.0 of 10 overall, with a Value score of 4.0.
