Don't expect too much warranty from products that ship from overseas from China. If you have a problem out of the box, you can connect the seller via AliExpress, they more than helped me once. But to give you an impression: of around 150 earphones, headphones and TWS I ordered from Ali, only ONE was broken out of the box. Only a generic 1,50 dollar earphone died on me, all the other products still work. :-)
