There was this guy I went to school with who always wore headphones so he wouldn't have to talk to anyone. They weren't plugged in.
"The idea of hearing the noises terrified him. The violent, shrill sounds his father said, a corpse emits during cremation. That's why our hero always wore his earphones. However, when someone he loves is brutally murdered, he takes a chance and cremates the body without his earphones hoping that what he hears will reveal who the killer is and not drive him insane. What he discovers shatters everything he believed in and trusted."
