Sound cuts in and out, game stutters

Hello, lately when I try to play HoTs with my razer kraken kitty headphones I have issues with the game (only a recent issue, used to work fine). The sound continuously cuts in and out, and goes back and forth through my desktop speakers and headphones. While this is happening my game is freezing. When I unplug my headphones and let it play through my speakers, the game is fine. I tried updating drivers, etc. Any ideas what is going on?
