Questions and answers
- Which sounds better for movies?
- The Sonos Era 300, because its angled drivers produce real height and rear effects. The JBL's Atmos is virtual and comes from a single front-firing cabinet.
- Which is louder?
- The JBL Authentics 500. Its 270 W amplifier and 6.5-inch woofer give it more headroom for large rooms.
- Can I use either with Google Assistant?
- Only the JBL Authentics 500. The Sonos Era 300 supports Alexa and Siri, not Google Assistant.
- Which is better for a Sonos multi-room system?
- The Sonos Era 300. It groups natively with other Sonos speakers; the JBL relies on AirPlay, Chromecast or Alexa Multi-Room Music.
- Is the JBL worth the savings?
- Yes if you want maximum output and both voice assistants. The Era 300 costs more but adds true spatial audio and Sonos grouping.
- Which has more wired connections?
- The Sonos Era 300, with USB-C and Ethernet plus a 3.5mm line-in through an adapter. The JBL has a single 3.5mm AUX input.
