This is a network streaming music receiver made by FiiO. I recently purchased it used at an auction, but since my old iPad did not support AirPlay 2, I was unable to output in high-resolution, so I am selling it. There are no problems with the operation of the main unit. Inputs: Wired LAN, Wireless LAN Outputs: USB, Coaxial Digital, Optical Digital - Brand: FiiO - Remote Control: Included - Connection Terminals: USB, HDMI, Optical Digital, LAN - Wireless Connection: Yes - Accessories: Power adapter, USB power cable *There are no noticeable scratches on the main unit, but the box has some tears. Thank you for looking.
