These hold a charge, good audio, pair and are in good condition with no major scratches or anything and include case (no charger included). HOWEVER when you open the arm with the charging port it shuts off. Sometimes just shuts off if jostled. I think loose connection? Sold for parts/ repair. I'm not sure the size 16 - 15s? but everything is pictured. Message me with any questions. Ships fast and free!
