Right now I only have headphones plugged in on the X11s and not the mic. Whenever I plug in the mic as well, people can end up hearing everything I hear.
It is only on this headset as I have another headset that is a different $20 one from walmart that works normally.

I was wondering if anyone knew if this was a common problem, or if there was a way to fix it.

These are originally made for the XboX 360, but they said that it can be used for the PC as well.

Thanks for any help,
Max
