I have a pair of Sade's 806, obtained them yesterday. The microphone works because I tested it in other ways. However it could be the method that I have the headset plugged in. I have an adapter on my graphics card through the hdmi that has an audio jack because my monitor does not have its own sound. the headset came with an adapter to plug in mic and audio into one 3.5mm jack but when I plug it into the adapter, sound comes out but no mic input can be heard.
