These sit in different size classes, so this is not a straight ranking comparison. The Amazon Echo Studio 2nd Gen ranks #2 of 15 powered desktop speakers by sound quality at $219.99; the JBL Authentics 300 ranks #46 of 112 boombox speakers by sound quality at $299.95.
Why pick the Amazon Echo Studio 2nd Gen: A great sounding Amazon smart speaker, with wide sound from one box, Dolby Atmos and a built in smart home hub. The catch: SoundGuys still marked it down on Value (4.0 of 10) given the $219.99 list price, and it is explicitly not true left-right stereo from one cabinet, so a stereo pair is needed for real width in a larger room.
The JBL Authentics 300 is the battery-powered choice. A retro styled smart speaker with both Alexa and Google Assistant, a leather handle and battery power. Its battery is rated for 8 hours, while the Amazon Echo Studio 2nd Gen needs an outlet. Watch for: Narrow sounding, bass not as deep as others.
Buy the Amazon Echo Studio 2nd Gen at $219.99 for a powered desktop speaker, or the JBL Authentics 300 at $299.95 for a boombox speaker instead.
