This is a wireless earphone from NOBLE FALCON. I have confirmed that it works properly. I used it for about a year, and the frequency of use was low, so I don't think the battery has deteriorated much. There are no major scratches, and the condition is relatively good. All accessories are included and will be shipped together. - Brand: NOBLE - Model Name: FALCON - Type: Wireless Earphones - Accessories: Charging case, USB cable, instruction manual, ear tips - Color: Black - Bluetooth version: 5.0 Thank you for viewing.
