1. Will it work with my Sonos setup?
   Yes if you have a compatible Sonos soundbar or Sonos speakers in the Sonos app. Pair it in the app and it becomes part of that room.
   
2. Is it truly wireless?
   Audio is wireless, but it still needs to be plugged into AC power.
   
3. Where should I place it for the best bass?
   Start near the front wall or beside your TV cabinet. Corners give more output, slightly away from the corner is usually tighter. Try 2 spots and keep the one that sounds smoother.
