This is a Sharp portable MD player, model MD-ST531-A. Due to its age, it shows some signs of use, with noticeable scratches and wear. The printing on the remote control is also faded. Upon inspection for this listing, I confirmed that it powers on and produces the startup sound. However, when an MD was inserted, no audio played, and the remote control displayed "No Disc," indicating that it could not read the disc. Therefore, I am listing this item as junk.
