Rat earbuds are earbuds made from a pair of ears off a dead rat's carcass, along with some spare wire. The ears of the rat function as the buds that go in your ears, while the wire functions as the cord and aux plug. Not as good as normal ear buds, but will do in a pinch.
Crafting requirements:
x2 severed rat ears
x1 spare wiring
x1 salvaged aux plug
Johnny broke his air pods and didn't have the money for a new pair so he fashioned himself a pair of rat earbuds for now until he gets paid on Friday.
