Hello, experiencing.

Thank you for visiting Apple Support Communities.

I understand that you are experiecing an issue with the sound quality of your receiver. Here are some troubleshooting steps that I would recommend going through in the article below.

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

If the issue persists, see the section labeled Get more help.

Cheers,

Jason H.
