Epoxy / adhesive for hard plastic (headphone hinge) ?

I have Skullcandy Crusher headphones and the hinge plastic broke. It's a really common problem with them. I don't need a hinge, I'd like to epoxy the hinge joint in the fully open position as it would be when being worn. I tried using 2 part epoxy to hold it together, but it wasn't plastic rated epoxy and it held perfectly for about 4 minutes, it was easy to pry off of the plastic and it was clear it didn't adhere well at all. I remember making plastic model cars and planes as a kid, the glue seemed like it melted the plastic pieces into one another for a really good joint, like a weld in metal. I don't know what grade the plastic they used for the joints is and I don't know how to find that information. Is there an all purpose adhesive or epoxy that I can use to make one big solid mass of plastic? Or do I pretty much have to try the various adhesives used for different grades of plastic? This amazon ad says Loctite Super Glue Plastics Bonding System with Activator 2-Gram (681925) Bonds plastics such as Plexiglas, polycarbonate, polystyrene, PVC, polyethylene, polypropylene and polytetrafluoroethylene (PTFE)/Teflon. Plus rubber, leather, cork, paper, cardboard, wood, chipboard, fabric, metal and ceramic. Loctite sells 2 different adhesives for these two different types of plastic The easiest way to identify a plastic type is by its label, commonly a recycling symbol. Plastics marked with a 6 or ?PS? are polystyrenes. These are used for simple items like disposable cutlery, plastic bowls, or fashion bags. For these, the best glue is a poly cement such as Loctite Plastic Bonder. Other types of plastic are used for tougher industrial or construction uses, such as drainpipes. Special plastics are even used for medical applications and bulletproof vests. For gluing these plastics, try Loctite Plastics Bonding System, which creates a powerful bond with just one drop.
