You can switch between wired and wireless setup if something changes in your home. Learn more about setting up your Sonos products.

Already have Sonos?

You can easily add a new Sonos product anytime—just plug it in, open the Sonos app on your mobile device, and tap > System > Add Product.

Add a different Sonos system
