GTX 980 TI 6GB

Hello, This is my first time using this forum site. This seemed like the perfect place to ask this question so here I go. I own a GTX 980 Ti Zotac AMP! (Non extreme) which is not exactly one of the best cards out there but should still be able to hold a decent core clock on the GPU regardless...

So basically I tried to use some Skull Candy earphones as a mic, they wouldn't work unless I put the headphone right next to my mouth and talk into it. So I bought a new microphone and now it is doing the same thing. It only picks up my voice if I put my mouth onto the headphone of the headset...
