Life Proof Nuud for iPhone 5 Sound issue

[Thisxisxlife]

I've been searching the forums for any answer to my situation, but didn't find any, so I apologize if this has been covered before.

Anyway, so basically when I'm in a phone call, people complain about how I sound. I even tested it myself, leaving a voicemail and listening to it.
However! When I hold the phone up to my ear and talk as if I were making a phone call, but I record myself in a voice memo, it sounds crisp and clear!!

Is there any explanation why the microphone would act any different between phone calls and voice memos?
Any help appreciated!

Edit: also sorry if this is the wrong section

Do you have good and strong service?

At the moment I have 4 bars yes. I've been testing the case and leaving voicemails for another phone. I noticed it was decent when I took the back of the case off and left the front on. Any possibility it has something to do with that?
