Ovann Microphone (3.5 mm) Not Working but Headphones Are

[star2777]

I'm using Windows 7 via Boot Camp on an early 2009 iMac and at the moment I am attempting to use Ovann X2-Pro headphones with the computer ( these are the headphones ) and the microphone is detected by the computer, but when I talk no sound is inputted.

The headphones have three plugs, two 3.5 mm line in plugs and one usb plug.

Can you right click the little speaker icon (probably lower right screen corner) and go into "Recording Devices"?

Select a device and click properties. Lots of setting there and it can be easy to miss something.....
