Replying to Broken headphones

i was borrowing my dad's professional headphones (sony MDR-7506) and i managed to fall and snap both of the plastic pieces holding together the ear parts. they are now crunched and detached and i was like oh FUCK! those were like $110 headphones. i immediately called the sony customer support line. the office that deals with that particular model is closed, but i predict i will have very little luck getting them to tell me how i can fix them since an essential part is literally shattered off.. does anyone know if this is something that may possibly be fixable? i'm in a temporary state of shock at my mistake. what do i do!!?
