I'm sorry to hear that Xiaomi earbuds 4 Youth edition trend Green is temporarily out of stock. This could be due to supply chain issues, production delays or high demand. As a popular brand, Xiaomi's products are often widely noticed and purchased. Therefore, when a particular color or model is out of stock, it may take a while to restock. It is recommended that you keep an eye on the news of Xiaomi's official channels or authorized dealers to get the latest inventory information. At the same time, you can also consider other colors or models of headphones to meet your needs.
