Thank you for viewing. This is a SONY wireless noise-canceling stereo headset. The details are as follows: * Model number: WF-1000XM3 * Color: Black * Included: Charging case, USB Type-C (TM) cable (approx. 20cm), Hybrid earbuds long (SS, S, M, L each 2), Triple comfort earbuds (S, M, L each 2) Purchased around 2021 for approximately 20,000 yen. I have only used it for about six months after purchase, so I think the sound quality is high. There is a scratch of about 2 cm on the top of the case and some scratches in the same place.
