I recently purchases a Sennheiser G4ME Zero to replace my Steel Series Siberia V3. The Siberia's microphone worked just fine along with the audio. When I plugged my G4ME Zero in the audio output worked great. When I tested out the microphone, my Macbook didn't receive any input. I plugged in my old Siberia to see if it was a hardware problem with the Mac but it showed up as a working external mic.
I've tried switching out cords, blowing out the input, and just plugging in the microphone portion to the computer but it still won't work. Is it a hardware problem with the headset or what?
