My brother-in-law's headset is messed up in such a way that people can hear him speaking into it, but he cannot hear them. After messing with it obsessively for the majority of the afternoon, he's figured out that it all comes down to... that's right, the blue wire. He's trying to solder the headset as we speak, but I think if it were me, I'd just buy a new headset! We're not talking about a Turtle Beach or any other expensive headset; we're talking about the cheapest wired one you can find!!
