Dec 18, 2014 6:41 AM in response to louisandsmitaby joe_7399,Hello louisandsmita,
Welcome to the Apple Support Communities!
If the sound quality the other party on a phone call is experiencing is not a quality that is to be expected, there may be a couple of different troubleshooting steps that I wold recommend.
The first steps I would recommend are the basic microphone troubleshooting steps for an iPhone and can be located in the attached article.
If your voice is too faint or sounds unclear using iPhone, or iPod touch - Apple Support
After completing the steps, if the issue continues, I suggest toggling the Phone Noise Cancellation setting on the iPhone. This can be found under Settings > General > Accessibility. Please let me know if the issue continues.
Use Accessibility features in iOS - Apple Support
Best regards,
Joe

Dec 18, 2014 11:07 AM in response to joe_7399by louisandsmita,Thank you. I just tried this.
I made identical, simultaneous recordings on my 6 and my wife's 6+. It's difficult to discern the difference in sound although the image generated while the recording is made is slightly more jagged on the 6+ than my 6.
I also noticed that at the same time that the symptoms I mentioned above started, during calls the network indicator says "LTE." I live in an area that has had ATT LTE data for some time, but may only recently have had VO-LTE turned on. So I turned off LTE for voice and made a voice call. The sound went back to the way it was before this past Monday.
I wonder if the VO-LTE sound quality is so good that it's picking up things I don't usually hear ????
