The type of headphones that poke really deep into your ear, to block out all other sound. If ears aren't cleaned regularly, they will attract earwax
Steve: Dude, I loaned Jim my ear-cleaners and when he gave them back, they were covered in his earwax...
Tomothy: ugh thats so gross, he should clean his ears more
its when you fuck someone in the ear till its squeaky clean and polish it with your cum
