Digital wireless audio system, ONKYO UWL-1(S) SILVER. - Brand: ONKYO - Model Name: UWL-1(S) SILVER - Included items: CD, cables, instruction manual - Type: Digital wireless audio system This system allows you to wirelessly connect speakers that do not support Bluetooth to audio sources such as a PC, enabling music playback. I believe all the basic accessories are included. (See the second photo) The color of the buttons has slightly discolored, but there are no noticeable scratches. Please be aware of this. I was using it until recently, and it worked perfectly fine. For your reference, based on my experience: There is no delay, and since it's for audio use, the sound quality is also good.
