Earmuffs

Does anyone know what sort of earmuffs I would need to purchase to block the noise of bunny whispers? I must slip a pair onto the human's ears right away. Really, I don't know why in the world she keeps letting those rabbits lounge on her bed. I'm sure they scatter carrot crumbs everywhere. She lets the lot of them stay there, though, and they just amused themselves whispering another idea for a bunny story to her. Is there no end to those things?
