Rare Sony CD Walkman. ATRAC3plus/MP3 compatible. The main body is made of full magnesium, so it is very thin yet strong, and has a high-quality feel. [Product Name] D-NE20 [Operation Status] This product was tested for operation using the battery box. The remote control works as shown in the photo, but it cannot play. It may be a problem with the remote control, as it sometimes turns on and off when the remote control is moved, but I have not tried purchasing a separate remote control to test it. (The inability to play may also be due to a malfunction in the CD player itself.) I would like to sell it to someone who knows more about it. The exterior is very clean with no noticeable dirt/scratches.
