Q: i cant hear anyone on the other end of my phone

Howdy lessie2004,

If the person on the other end can hear you but you can't hear them, please step through the suggestions in this article.

If you can't hear a person on a call or voicemail or if the sound quality is poor on iPhone - Apple Support

It has several things to try.

Thank you for thinking of Apple Support Communities for your support needs.
