Thank you for viewing. This is a listing for Sony wireless earbuds. I put them away after using them for several years, but I'm selling them now because I no longer use them. I have confirmed that they can be charged and used before listing them, but I haven't checked how long the battery lasts. Also, there are minor scratches and signs of use, so please check the photos. The charging cable etc. are not included, only the main unit, so please consider this before purchasing. MDR-XB50BS
