I found this while organizing a drawer in a shelf at home. It's a remote control and earphones for a portable MD player that I used to own. I don't have an MD player on hand now, so I haven't confirmed that they work. As shown in the 7th photo, part of the rubber at the base of the earphones is missing. There are also parts where the Pioneer lettering has peeled off. Due to long-term storage and the fact that the operation has not been confirmed, no warranty of any kind is provided after purchase. Thank you for your understanding.
