These actually do work as far as I know. They are missing the round leather or foam piece that covers the earphone and goes around your ear. I think they can be replaced. And the right side has a part of the headband that has been glued. Other than that everything works great. And neither of those things affected the usability.u can still use them even if you don't get the headphone ear cover things. They actually are still comfortable.they have a microphone that pulls out of the lower left outside of the  headset. The microphone's on/off and volume control are down about an arms length down  the connector cord.these are great gaming heads phones and even though they are well used they are still ingood shape and work great.
