This is an ELECOM Type-C to 3.5mm audio conversion cable. It converts the Type-C port of a smartphone or tablet to a 3.5mm stereo mini-plug, allowing you to connect wired earphones or headphones. I accidentally purchased this and opened the package, but it is unused. There are no noticeable scratches or stains, but please understand that this item has been stored at home before purchasing. Thank you for looking.
