In the new model of Apple iphone 7 and 7 plus some user have
reported some disturbance or Static while making a call. Other person in the call
is not able to hear properly. The problem is reported in recently purchased
mobile phone as well, so cannot be a iOS software upgrade issue. However Apple have
not issued a public statement on this but when some users complained about it Apple
has just refused this to be a software issue rather pointed as external
surrounding issue.
If you are also facing
this issue below are few fixes for iphone bad sound over call :
Ø Restore iphone from iTunes: Back up and restored
the phone to factory settings using iTunes. After this restore the backup. This
may fix the issue and you should test this for few days.

should get you a new iphone as replacement.
Ø WiFi – Modem issue :
Are you using your phone over Wi-Fi? The iPhone 7 uses WIFI for
calling if it is available and it is generally a much better signal than over
the air. So if you have modem and is not

worked for few user and fixed the issue permanently. Or try
disabling Wi-Fi Calling.

reason for bad quality sound in you iphone can be due to 4G settings. Check if
4G service is interrupting the signal

options>Enable 4G> click on OFF.
Ø Try using the 'speaker' option or bluetooth
earpiece to see if it's related to the phone's microphone?
