Sonos speakers are weird and I don’t get the hype. They’re not Bluetooth, so playing anything on them has to go through the Sonos app and server. Sonos is also a shady company, doing things like bricking your device if you try to sell it after upgrading, or not letting you use your speaker if you disagree with their privacy policy.

Imho, a speaker is an electroacoustic transducer, converting electric current into sound, or at least anything that can output the sound of arbitrary input devices.

If it has apps, then it's instead a computer or a stereo system with built-in speakers.

So I find speakers a misleading name for this contraption, unless it has an input of some sort that you can connect what you want to.
