widespreadCause: Spotify and other services do not support spatial audio through Sonos - major limitation for $449 speaker
Sonos app frequently disconnects from Apple Music account
commonSetting up on guest network or with range extenders
Setup fails completely - Era 300 requires direct connection to main network
Tip: Use your primary home WiFi network. If issues persist, set fixed channels for 2.4GHz and 5GHz bands.

No. Google Assistant and Chromecast were removed from Era series. Only Amazon Alexa and Sonos Voice Control are available for voice commands.

Sonos SupportCause: App stability issues after 2024 update cause playback failures and account disconnections
Line-in and Ethernet require expensive adapters ($19/$39)
widespreadCause: Cost-cutting decision to lock basic connectivity behind additional purchases
Spatial audio quality inconsistent across albums
commonCause: Some Dolby Atmos mixes feel overengineered or all-consuming rather than natural
Placing speaker against wall or in corner
Spatial audio cannot properly reflect off ceiling and walls - immersive effect is lost
Tip: Position with space around and above the speaker. Upward-firing tweeter needs clearance for proper Atmos effect.
Sonos Voice Control processes all requests on-device - no recordings retained. Location tracking required during setup.
Physical security switch disconnects all power to microphone. Separate voice services button for convenience. Mozilla Foundation has flagged Sonos for privacy concerns.
You want a single premium speaker for music
Excellent sound quality, but $449 is steep unless you regularly listen to Dolby Atmos content
Not simultaneously. You must choose one configuration. Switching between stereo pair and surrounds requires reconfiguration in the app and loses Trueplay tuning each time.
