JBL Authentics 300 vs Klipsch The Three Plus

Last updated: October 29, 2026

Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Authentics 300 ranks #46 of 113 boombox speakers by sound quality at $299.95; the Klipsch The Three Plus ranks #25 of 29 powered desktop speakers by sound quality at $274.99.

JBL Authentics 300 vs Klipsch The Three Plus

The JBL Authentics 300 is the battery-powered option. 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 Klipsch The Three Plus needs an outlet. It streams over Wi-Fi as well as Bluetooth, which the Klipsch The Three Plus cannot. Watch for: Narrow sounding, bass not as deep as others.

What the Klipsch The Three Plus does well: A retro tabletop speaker with a built in phono input for a turntable, plenty of volume and optical and USB-C inputs. The tradeoff: The tuning leans heavily on bass: TechRadar called it on the warm side of neutral with the treble only just holding its own, and HomeTheaterHifi found the treble turned sharp and piercing at higher volumes.

Buy the JBL Authentics 300 at $299.95 if you want a boombox speaker. Buy the Klipsch The Three Plus at $274.99 if you want a powered desktop speaker instead.
