I am selling this item because I purchased a new one. I used it for about three weeks. All accessories are included (charging case, cable, instruction manual, etc.). There is almost no sign of use, and there are no noticeable scratches or stains. Returns are not accepted to prevent any problems. Please check the photos and description before purchasing. These are wireless earphones that support LDAC and high-resolution audio playback, with wear detection. Model name: EarFun Air Pro 4
