PSP dedicated remote control headphones and a strap. These were included in a box of miscellaneous items, so the details are unknown. It is specified for PSP-1000, but it might also work with PSP-2000 as they have a similar connector. (This is the seller's speculation and does not guarantee functionality.) Headphones or earphones are not included. The details of the strap are unknown. It has the △□×〇 logo engraved on it, so I think it's a PSP-related item.
