When talking about Sonos, we have to be careful about the use of the words paired, bonded, and grouped, as they have specific meanings in the Sonos ecosystem. When you use the term ‘paired’, you should be talking about a stereo pair, left and right. When you say ‘bonded’ you’re talking about a special connection between speakers, like a sub, or surrounds connected to a Sonos soundbar. The term ‘grouped’ means you have several ‘rooms’ in the Sonos software connected so they’ll play the same music.

Only speakers of the same type can be paired. This means you can’t create a right/left pair using a Move and a One. You can group them, however, and they’ll both play the same signal.

If you don’t use any voice control system, then you’re smart not to pay for the functionality you’ll not use, I’d definitely stick with the Sonos One SLs.

Thank you for the clarification Bruce. I didn’t realize the difference when using the terminology. 
So if I were to buy another Sonos One SL it cannot be use with the Move as stereo if I wanted too? But of course I would be able to use both together. It just won’t have the stereo sound? 

You can ‘group’ a Sonos Move with a Sonos One, and they’ll both play the same audio in sync. You can not ‘pair’ a Sonos Move and a Sonos One and have one of them be the right speaker and the other be the left speaker. 

They’re sonically different, and Sonos considers it to be an issue, so they don’t allow ‘pairing’. There may be third party apps that do but I’m not familiar with them, so don’t really know. 

How do I group a move and One SL and make this group an option for Airplay?

Here is how to group and up group rooms in the Sonos system.
