This does not only relate to headphones, but also to earbuds that you connect to your laptop or phone. The trouble with headphones is that they are capable of producing very loud sounds very close to your eardrums. The hair cells will translate these movements into electrical impulses that get transmitted to our brain via our eighth cranial nerve. Ultimately, with long-term exposure to long noises – and thus, strong vibrations – these hair cells will eventually lose their sensitivity to the vibrations. Earbuds and headphones are exposed to germs, especially when you do not keep them away properly, but just leave them lying around.
