Hey, Buddy,
I have the same Headphones and faced the same issue at the same place,
what I did was, I made two creases parallel to each other that would fit a 1.5" metal wire.
I placed the metal wire in the crease, half of the wire on the head rest part and the other half on the ear rest part, so that it would hold together, then I used superglue on it,
normal super glue does not work, even in my case it didn't, but when you put baking soda on the superglue before it dries, it will make a strong bond and will last longer.
so try the trick with baking soda on the superglue.
Hope this helps you with your Issue. Thank you!
