This is a set of three items: earphones, a charging cord, and the instruction manual. I used them once or twice, but I'm selling them because I stopped using them. The film on the battery level monitor hasn't been peeled off. I punched holes in the instruction manual, so please refrain from purchasing if you are concerned about this. They don't completely block your ears, so you can use them while being aware of the surrounding sounds. The following content was created by AI, so please be aware that there may be errors.
