High-quality wireless earphones with a 320mAh battery. - Brand: SONY - Model: WT-1000XM3 - Battery Capacity: 320mAh - Color: White Thank you for viewing. This is a junk item. While other functions are not problematic, the battery life for charging is poor. Both earbuds die after about 30 minutes. As I have discarded the box, etc., only the charging case and earphones are included. Please purchase only if you understand that this is a used item.
