I have Huawei headphones. Purchase date: 16/6/2026. I've used them for approximately 40 days since purchase, no more than two hours. I want to sell them because they didn't suit me. I use Apple and decided to try them. I bought them for 600, and the sale is by auction. Bids less than 400 are not accepted. The invoice and warranty are available. Location: Eastern Province - Al-Ahsa - Al-Mubarraz
