Thank you for viewing. These are wireless earphones. I received them from an acquaintance who bought new ones, but I don't use them, so I'm selling them. My acquaintance was able to use them without any problems, so I will not be testing them myself. Please understand this before purchasing. I have many other items for sale, so I would be happy if you would take a look. If you purchase multiple items, I will offer a small discount. They will be shipped via Yu-packet Post.
