Glue problem

[ANDY M]

I have an old pair of Sennheiser headphones that work great, but the plastic broke where the can is connected to the head strap.
I spoke with the manufacturer and they weren't much help. Crazy glue or Super glue (Cyanoacrylate) reacts with the plastic and it won't bond. In fact, it won't even dry. I also tried a two stage epoxy, which took over a day to dry and then held up for only a few days.
Any suggestions? [img]<<GRAEMLIN_URL>>/dunno.gif[/img]
I really don't want to buy a new pair. Dr. Dre has enough money already. [img]<<GRAEMLIN_URL>>/mad.gif[/img]

Thanks,
