Mini. Fits in any space, fills any room. Mighty. Surprisingly rich sound despite its size. Humidity resistant. Perfect for the bathroom (or backyard). Two PLAY:1s work as Sonos home theater rear speakers. Wall or stand mountable. Streams over wi-fi, not Bluetooth, so the music never stops – even if you get a phone call. Connect Sonos to an Amazon Echo or Dot, then simply request the music you love.
