Approximately one year has passed since the purchase, but I've only used it outdoors about 2-3 times. I've mostly used it indoors, about 1-2 times a month for an hour each time. There are no noticeable scratches on the headphones themselves, but the case has a small black mark of some kind on the back. Basically, only the items in the photos are included (the instruction manual and the wired connection jack are included). The Type-C charging cord is missing and will not be included. Operation confirmed. If you have any questions, feel free to comment. I want to sell it quickly, so you can negotiate the price in the comments section.
