The scheme is currently open to Connect, Connect: Amp, ZP80, ZP90, ZP100, ZP120, and Play: 5 first generation owners. If you’re one of those early adopters, you can track an upgrade process through the Sonos app.
The My Account section displays a trade-up area where you can select suitable devices to exchange for funds. You get a 30 percent discount on a new device for each upgrade, and 21 days later your current speakers go into recycling mode. This will delete your data from the device and permanently disable it. You can then take it to your nearest e-recycling center to dispose of it or send it back to Sonos.
