Have had vibration/ringing in my ear for past couple of weeks,mostly at night. had this before but it seemed to self correct after stopping earphones.

Hair cell damage: The most common reason for ringing or tinnitus is hearing loss. You brain tries so hear to that it starts “hearing things” or creates that ringing. The reason it improved after stopping the earphones is because you gave the hair cells in your ears a chance to recover. Short term noises cause a temporary hearing loss but over a long period or loud enough noises can cause permanent hearing loss
