A:Answer You have several options for connectivity but for Bose to Sonos, it is limited to one: Airplay 2. As long as your devices have Airplay built in, you can listen to many of them (I have 7 in total) without any issues.
With new Bose speakers, you can use the app to listen to multiple bluetooth speakers but this is only possible using the Bose app. It is a software trick. You can not do that with this speaker. If you are using bluetooth and Sonos, you are limited to only one speaker.
