It works without any problems. I bought it about a year ago, but I only used it for about 3 months. There are two scratches. Please see images 3 and 4. I don't think the battery has deteriorated much since I didn't use it very often. Everything in the pictures is included. - Model Name: WH-1000XM5 - Color: Black - Accessories: Case, cable, outer box - Brand: SONY - Ear Pad Material: Soft cushion Thank you for looking.
