I bought Bose Quiet Comfort 25's and I wanted to use the inline microphone on my PC, so I bought the Startech 3.5mm 4 pin to 2x 3 pin 3.5mm headset splitter, plugged it in, and the audio works, but not the microphone, its only static, I've uninstalled and reinstalled audio drivers, messed with setting, ect. I also used to have Virtual audio cable if that helps.
