Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Authentics 300 ranks #32 of 75 boombox speakers by sound quality at $299.95; the Sonos Era 100 ranks #12 of 16 powered desktop speakers by sound quality at $219.
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.
The case for the Sonos Era 100: RTINGS lists room correction tools and bass/treble adjustments as its real strengths, and its balanced midrange suits a wide range of genres, with wider stereo separation than the mono Sonos One SL it replaced thanks to two angled tweeters plus a 25% larger mid-woofer than the original Sonos One. The tradeoff: RTINGS’ own two listed cons are not loud enough for larger rooms and very little low-bass thump, so genres like EDM and hip-hop lack rumble even with the tone adjustments.
Buy the JBL Authentics 300 ($299.95) for a boombox speaker; the Sonos Era 100 ($219) suits a powered desktop speaker instead.
The Sonos Era 100 is not a sound-quality pick. It sits near the bottom of the 16 powered desktop speakers; there are better options higher up.

Sonos Era 100: $219.00 each Amazon eBay
Pros: RTINGS lists room correction tools and bass/treble adjustments as its real strengths, and its balanced midrange suits a wide range of genres, with wider stereo separation than the mono Sonos One SL it replaced thanks to two angled tweeters plus a 25% larger mid-woofer than the original Sonos One. Alexa is built in with a far-field mic, and it ties into the wider Sonos S2 app ecosystem for multi-room audio.
Cons: RTINGS’ own two listed cons are not loud enough for larger rooms and very little low-bass thump, so genres like EDM and hip-hop lack rumble even with the tone adjustments. There’s no Google Assistant, the USB-C line-in needs a separately purchased adapter, and there’s no battery.
