I bought a Redmi 8 and the Mi Dual Driver Typ-C earphones. Earphones didn't work, so I wrote to support. After 5 days, they still did not answer. I sent further 3 emails, no reaction. I wrote in Chat support. After about an hour, the support agent told me, this very earpads are not compatible with redmi 8 but on their site they don't mention which earphones are compatible with what phone. Now, they refuse to get these earphone back and sent me a pair they is compatible. They say, we are not the official xiaomi site, we are just a shop, if you want to see what is compatible, you will have to visit the official xiaomi site. Here te original text fro chat "Wir sind nicht Xiaomi selbst. Wir sind ein Händler der die Lizenz/Berechtigung zum verkauf von Xioami Artikeln hat. " Now I know why xiaomi devices are so cheap. Avoid the Swiss Mi-Store!!!!
