I have the XS Max and use the audio official apple dongle. Every now and then after the call, the voice on the headset goes blank and the phone behaves as if there is no headset connected. Even if I remove the headset and reinsert it, it makes no difference unless its rebooted. what is this? horrible quality --- Post Merged, Sep 30, 2018 --- The port still charges just fine but the headset has no sound as though nothing is connected.
