anscheinend haben die Entwickler kein Interesse daran, hier zu Supporten. Mich würde ebenfalls interessieren, wie man die earfün pro2 updaten kann.

Vielleicht kann irgendwer darauf antworten.

I am very disappointed with the sound quality on these earpods. I am hoping that this firmware upgrade would help. I have 30 days to return these and  intend to do so if something doesn't change. I hope you are able to fix this problem quickly. The fact that my English language app is presenting chinese characters doesn't leave me with high hopes.
