Query: Nice sound, poor construction.

I got these last December-05. The molded plastic that holds the ear cups onto the headband started to crack (right at the L/R labels). They eventually crumbled and fractured, causing the cups to fall off. I taped one side up and the other failed as well. I have no doubt that if I replace these, the same thing will happen. My complaint is for $300 I expect something other than soft plastic holding these together at the stress points.
