Only to the Sonos which support Bluetooth, which are the Move, Roam, and Era series. In addition, the Roam and Eras can group with other Sonos speakers to play Bluetooth audio to the group.
One small caveat, when set up as ‘surround speakers’, the Bluetooth input is turned off. For the speakers listed by @jgatie , only the Era speakers can be put in that kind of position.
