A:Answer Hi!
You can pair/link together 2 of our S1 Pro speakers in a party mode through the Bose Connect app.
When paired this way, you can select for this to play through Stereo or through Mono audio between the two.
From here, you can pair this up to a compatible Bluetooth device (Such as a Smart TV) any play audio from this.
Please note that there may be an audio delay if you are using this through Bluetooth, so please check for any video delay, or video/audio sync options within the Smart TV/other device in order to have the best experience.
We hope this helps!
