Some iPhone 5 terminals have problems maintaining the quality of audio calls in areas with a lot of background noise

  In the iPhone 5, Apple implemented no less than 3 microphones to offer users very good quality audio calls. Although the device is also compatible with HD Voice technology, it seems that it exists certain problems when using the terminal in areas with a lot of background noise. In these situations, the quality of the calls becomes precarious, the users stating that they hear what the interlocutor says as if their ears are "clogged", but they come back and say that everything only happens when there is loud noise around the user, or when he is in walking

While talking over the noise was louder around me than I had a feeling of plugged ear, as if I were inside a bubble. It's something annoying that led me to hang up the phone. The day after continuous testing outdoors, I go to a town center and much as I walk and I talk about the strange sensations that lead me to almost have a headache. We're at 3 iPhone 5 to 3. I try to call two other friends and ask them to try to see this thing, I confirm now, they also had the strange sensations in some situations, we are at 5 of 5.

  I am curious if you have experienced problems of this kind with iPhone 5 terminals because Apple does not seem to have recognized the existence of such a problem for now. On discussion forums of Apple there are quite a few people who complain about similar problems, but for now nothing seems to have been resolved.
