I can inly hear sound coming from my right ear on my headset. I dont know how i can get to the mother board on a steel series siberia V3. I have tried tofind like a sweet spot but it doesnt work and i have tried to put the cable out and in. I have also tried to plugg it in from behind my PC and it doesnt work.... Or do anyone know how i can open the ear things to get inside the headset on the side that i cant hear anything?
