I was on Paranoid Android (it has happened on stock and CM)

My friends were complaining about my phone quality who some have all carriers, Sprint, AT&T, and Verizon. Some phones they were using were Motorola RAZER V3, Galaxy S3, Note 2, Note 3, iPhone 4s, iPhone 5s, and HTC EVO 3D. When I hear them it is crystal clear but when I talk it all muffled. I called myself from google voice and as far as I could tell I sounded clear.

I've tested physical mic quality and it sounds fine (with a sound recorder app)

I've tried latest and proper radio/rom

How can I fix this?

I have T-Mobile, and I've tried while under T-Mobile and AT&T same problem
