Sonos isn’t Bluetooth speakers, they have a couple in their portable lineup that do offer Bluetooth, but last I checked the majority don’t offer Bluetooth and to be honest I like it better this way.

Not having my phone locked up to only play music is awesome, being able to use voice control to play specific songs and have them play throughout the house is awesome. Bluetooth is a pain, not being able to use Instagram (or any other app that wants control of audio) while my daughter listens to a song sucks.
