Foldable Rear Band Headset (Coquitlam Maillardville)

Hello, a headset With a mic, that an older sibling used to use, MORE THAN A DECADE AGO, when she used to be a high school online school teacher

Saw that she was going to trash it, and my HOARDER INSTINCTS JUMPED INTO ACTION and kept it in my desktop drawers for the past FOURTEEN TO FIFTEEN YEARS with NEVER USING IT, NOT EVEN REMEMBERING THAT I HAD KEPT IT IN THERE!!!

I tried opening it up, and it seems to be in good condition, AND I just tried plugging it in to see if the headset actually still works, and music still flowed out! I am going to assume that the mic should be good as well
