I purchased this product new in February 2024. I subsequently became very fond of the product and used it until December 2025 (using it about 5 days a week). I have now decided to purchase different earphones, so although I still like this product very much, I have decided to put it up for sale. I used it for about 1 year and 10 months, but there are no problems with its operation, and I don't feel that the battery life has shortened. If anyone is interested, please consider purchasing it. *I do not smoke, and I do not have any pets. *As shown in the photos, there is a scratch-like mark near the "HUAWEI" logo on the case. *The charging cable has never been used and is in new condition. If you have any questions, please feel free to send me a comment. Thank you very much.
