Unhappy LG G2 D802 Headset mic problem

Hello Helpers,

I have LG G2 D802 Stock 4.2.2

Frustrating problem is when i plug in my headset and talk to someone over headphones they barely listen my voice i dont think they can hear my voice well, i even changed my entire hardware but still no luck. could you android gods help me over this issue?

Thanks in advance.
