Huawei bluetooth headphones?

I bought the Bluetooth headphones from Huawei two weeks ago. So far everything has always worked, but now I suddenly can't connect it to my cell phone. You are charged and still working yesterday.

Unfortunately I have no instructions that I can look up. Do you have an idea?

Freebuds 3?

Freebuds Lite

Very easily.

Test the headsets on another smartphone. Girlfriend. Doesn't have to be Huaweih. The main thing is Blutooth.

If they sparkle there, the Smatphone is the culprit.

Vice versa. Test other headsets on your Huaweih.
