Ok so I bought a pair from a guy who had the cup break but nothing else was broken.
So what I did, took it apart and then messured the hole around the break, took a thin piece of plastic and shaped it so it fitted snug around the part that sticks into the broken cup. Now to the part that makes it unbreakable again. U will need any kind of plastic superglue (gorilla glue etc) and bakingpowder. So put glue and powder in a small container that u can throw away, now u need to be fast. Mix glue and powder and then put in the hole and glue the plate and headphoe pin into the cup again, the glue and powder will turn into a plastic cement. The only loss u wil have is the little wiggle u can do with the earcup left and right. But u saved your headset. The mixture is also repaintable with a common magic marker.
