Steps

1

2

4
Scroll down and slide the “Phone Noise Cancellation” switch to the off position. This switch is in the third section, under "Hearing."
- Noise cancellation is turned on by default in iOS 10.
- If turning off Noise Cancellation doesn’t improve the sound quality of your calls, there could be a problem with your earpiece. To contact Apple for assistance, see http://www.apple.com/contact/.^{[1]
