These are not really the same size class, and that is the honest framing here. The JBL Authentics 300 ranks #46 of 112 boombox speakers by sound quality at $299.95; the Sonos Move 2 ranks #28 of 117 large speakers by sound quality at $480.
The case for the JBL Authentics 300: A retro styled smart speaker with both Alexa and Google Assistant, a leather handle and battery power. It links with other speakers (Wi-Fi Multi-Room), which the Sonos Move 2 cannot. It has an adjustable EQ, which the Sonos Move 2 lacks. The tradeoff: Narrow sounding, bass not as deep as others.
The Sonos Move 2 is the longer-running, lighter choice. A Wi-Fi and Bluetooth portable with warm, full sound, clear mids and a long battery for moving around the home. It is rated for 24 hours of battery against 8 for the JBL Authentics 300. At 6.6 lbs (3 kg) it weighs much less than the JBL Authentics 300 at 10.8 lbs (4.9 kg). It is rated IP56, while the JBL Authentics 300 has no water resistance. Watch for: Not very loud.
Buy the JBL Authentics 300 at $299.95 if you want a boombox speaker. Buy the Sonos Move 2 at $480 if you want a large speaker instead.
