Ever notice how those Microsoft headsets always come out with thinner and thinner wiring that is bound to break, that's because they want you to buy a new one every year, We all have broken our headset and hear is a way to bring it back to life
this headset was broken and useless, now it serves its purpose
I built the mic into the adapter next to the mic icon, and the black add on piece is fully detachable and transfers the audio to a 3.5 mm headphone jack, i wouldnt need it if i had a import 3.5 mm jack coming out of it. You can also wire headphones directly into it like the black wire but it is more compact if you want the audio coming out of the tv
