The Ones aren’t designed to be used as your primary TV speakers. But they can be used with TV audio if they are bonded to a Sonos home theater device (like a Sonos Ray) as surround speakers.

If they Ray supports surround then you can bond the Ones, if you have to group the Ones it will sound terrible (due to the delay).

Thing with using as surrounds you only get surround audio.

But you can also play music through the combination of Ray and Ones.
