final ag COTSUBU AG-TWS09R [Set Contents] ・Earphone body ・Charging case ・USB-C cable ・Ear tips (SONY S size *new) I stored these after hardly using them after purchase. I charged them and used them for 2 hours, and the battery level was 76%, so I don't think there's much degradation. The case has some black marks due to color transfer during storage. The earphones themselves are in a clean condition. I'm including SONY S-size ear tips. 3005101
