Purchased about two years ago and used for an average of 3-4 hours a day for about six months, alternating with another model. There are some scratches and wear and tear from use. There are no problems with its use, and it can be used without any stress. I haven't used it for a while, but I'm selling it to organize my belongings. I think it's a very good product with good performance and a small size. I've never worried about the battery running out. It's so small and light that you barely feel like you're wearing it, and it's comfortable if you adjust the ear tips, so much so that people often drop them without noticing. I will include unused ear tips from another manufacturer. The red color is cute. Thank you.
