Thank you for your questions. Arc plays music, and send surround sound wirelessly. However, wireless audio transmissions, and power are not really a thing yet. So Arc does need to plug in for power and one cable to the wall. There are kits you can buy that are like plastic tunnels (for lack of better word) and stick to the wall, and have a cover to hide the cables. You can paint over them, too. There are also many in-wall power kits too. Let us know if you need anything else.
