Question [Q] Headset Mic. Problem

Hi All

I think my Nexus 4 device has a problem with headphone-in jack. I don't have any issues with devices own michrophone but when i plugged in my headphones my voice is too low on other side. I tried to change Rom and Kernel. But it looks like a hardware problem. Using Purity And Hells right now, is there any way to increase the microphone sound level?
