This is the Sonos One SL model which is missing smart assistant features (microphone-free version).
20c cheaper than this deal or the same price depending on how you look at it.
Apparently if you already have a Sonos One gen 2 you can pair this speaker to get stereo sound & keep the smart assistant functionality from your original Sonos One gen 2.
Also speaker is humidity resistant.
The following is copied & pasted from previous deal:
The powerful microphone-free speaker for music and more. Get rich, room-filling sound with Sonos One SL, and control it with the Sonos app, Apple AirPlay 2, and more. This compact designed speaker fits just about any space. Put it on your kitchen countertop or tuck it away on your office bookshelf. It's humidity resistant so you can even put it in the bathroom.
Pair with Sonos One or another One SL in the same room for stereo separation and more detailed sound. Use a pair as rear home theatre surrounds with Playbar, Playbase, or Beam.
Stream sound directly from your iPhone or iPad and ask Siri to play Apple Music with Apple AirPlay 2
Wirelessly connect a voice-enabled device, such as an Amazon Echo Dot or Google Home Mini, for hands-free control of your music and more
Play, pause, skip tracks, adjust the volume, and group rooms just by tapping or swiping with capacitive touch controls
