How does Brian hear in that costume? It seems like the head piece completely covers his ears. Furthermore, the position of "Shrek's" ears do not align with the position of where Brian's presumably are. What gives?
You'll find out on the new season of Nip/Tuck.
there are thinner sections of the costume above where his ears are.

Yeah, in person it looks like it's just mesh in those places so the sound can get through.
