Mobile does not recognize headphones (USB TYPE C)?

Have the Huawei P20 and have known that no AUX connection.

Since headphones and an adapter with the USB type C were delivered, so you put it in there where the charging cable comes in synonymous. Everything worked great in the beginning. Only now he suddenly does not recognize the headphones and plays the music as normal with the speaker. Charging cable works normally. That means it's not the hole, but not the headphones, because others do not work.

Bluetooth headphones work, but that is super corrosive to charge constantly.

Has a NEN proposal? Guarantee is no longer there.

Look, whether your headphones on other devices with normal jack socket work (computer, older phone). If so, it will be the adapter from the phone.

Have such a thing too and it makes a very unstable, short-lived impression.
