Voice on calls are too quiet I got a new phone and sometimes it's hard to hear the person on the other line. Sometimes people say it's hard to hear me. This is a high end phone and I don't think this should be happening. What options are available to change? I've pressed the volume-up arrow to the top when I'm on a call and it's still too quiet.

What exactly do the options: Speaker voice enhancement, equalizer and microphone noise suppression do?
Audio volume during phone calls appears to be a common complaint made by many Sony users.

I recommend turning off all the extras/enhancements to make a final determination regarding call volume. A different device may be better for you.

Below are the various options described:


Speaker Voice Enhancement provides "richer" voice listening during
phone calls (impacts what you hear). Turn this off.
Equalizer fine tunes the pitch of the call audio (impacts what you
hear). Turn this off or choose the most level/smooth option.
Phone Noise Suppression reduces background noise on your end (impacts
what other people hear). Turn this off if other people can't hear you
or experience breaks/skips in your voice. This feature may be useful
when you are outside.
Enhanced Voice Privacy provides an additional layer of voice
encryption (impacts both sides of conversation). Turn this off if the
option is available.
