SONY wireless earbuds, charging case, and all accessories included. Purchased around 2022, used for about 3 years. There are some signs of use and scratches, but there are no problems with the operation. I used other ear tips. The S and L sizes are new and unused. A charging cable is also included. The battery has deteriorated due to aging. During use, the left earbud sometimes malfunctions with accidental taps. There are no other problems with the other functions. Please consider this as a junk item as a precaution. When a malfunction occurred, I requested repairs from the official SONY service, and I have not disassembled the item myself. Since this is a used item, I would appreciate it if you could purchase it if you understand this. The case I was using will be included. The ear tips shown in use are not included. I am not considering price reductions. I will ignore requests and comments, so please understand. - Brand: SONY - Model Name: WF-1000XM4 - Type: Wireless Earbuds - Color: Black - Charging Case: Yes - Other Features: Noise Canceling Thank you for viewing.
