Solution 1: Disable Phone Noise Cancellation
- Go to Settings->General->Accessibility.
- Scroll down to find “Phone Noise Cancellation” and turn it off.
- Turn on “Hearing Aid Compatibility”.
Solution 2: Turn off Bluetooth
This issue may occur if your device sends audio to bluetooth accessory.
- Launch Settings->Bluetooth.
- Turn off Bluetooth.
Solution 3: Increase the volume
- Go to Settings->Sounds.
- There you can see the Ringer and Alerts slider. Drag the slider to increase the volume.
- Enable “Change with Buttons” and check the sound.
- Adjust the volume using volume buttons while speaking on phone call to check the sound.
Solution 4: Check for Software Update
- Connect your phone to Wi-Fi or Cellular Data.

- Drag the slider to turn off your device.
- To turn on your device, hold down the Power Button until the Apple Logo appears.
Solution 6: Check and clean the receiver
- Make sure that nothing is blocked the receiver.
- Make sure that nothing is plugged into the headphones jack or the dock connector.
- Clean the receiver with a clean, dry, small, soft-bristled brush to remove the debris.
- Remove the screen protectors, case, and films from your iPhone. Because they may cover the receiver or microphone.
Solution 7: Check the Microphone
- Launch the Voice Memos app and record your voice.
- Play the recording.
- Check whether you can hear your voice clearly or not.
- Open the Music app and play the song. Now find if there is any problem with microphone/speaker.
Note: If you can’t hear your voice/music clearly, the problem is in your phone’s Microphone.
- This may be a network issue. So make calls from different locations
- Check Apple warranty status. If your iPhone covers warranty, take it to the Apple Service Center.
- Make an Apple genius bar appointment.
