Joel,
There aren`t any methods via IR. You can shoot an RF (Radio Frequency) signal over the air.
However, you still need to get power to your speakers in those cases to amplify the sound…so you still need a wire. A battery operated speaker wouldn’t be too practical or have very good qualities.
We don`t have anything wireless for inwall.
