● Usage Period: Purchased approximately one year ago and used for about 30 minutes almost every day. ● Condition: Works normally. I believe there are no noticeable scratches within the range I could see. Regarding the battery condition of the earphones themselves, I haven't used them continuously until the battery runs out, so I don't know how many hours they last. However, for short-term use like mine, charging the battery case was sufficient, and I only did it occasionally. Also, the product has been disinfected. ● Other Notes: Inspection has been carried out, but please forgive any oversights. This product is available for immediate purchase. Please consider this a used item.
