Wired MI earphones with metal earphone heads, 3.5mm plug, and a storage case included. - Brand: Xiaomi - Color: Gold/Black - Design: Metal earphone heads - Connection: 3.5mm plug - Accessories: Storage case These are the legendary Xiaomi Piston earphones, which demonstrated the amazing quality of Chinese earphones to the world. They appear to be a commemorative edition, making them very valuable. Purchased around 2014, when Xiaomi was hardly known in Japan. I bought them at an official store during a trip to Taiwan. While they show signs of use, I have confirmed that they produce sound normally. These are used items stored at home, so please refrain from purchasing if you are sensitive to such things. *Due to the thickness of the product, the cover case lid will be removed, and the lid and bottom will be laid flat for shipping. Thank you for viewing.
