Wearing headphones for a long time may lead to auditory nerve damage, cerumen impaction, otitis externa and so on. 1. Hearing nerve damage: As a result of wearing headphones for a long time, the noise stimulation may damage the cochlear hair cells, and the damage caused by the cochlear hair cells may easily lead to hearing loss, tinnitus and other symptoms. 2. Cerumen embolism: mainly due to wearing headphones for a long time, the secretions in the ear canal cannot be discharged normally, thus causing cerumen embolism. 3. Otitis externa: Because wearing headphones for a long time will cause direct stimulation to the skin of the external ear canal, it will trigger inflammation of the external ear canal, which may lead to ear canal pain, pus and other symptoms. It is recommended to avoid wearing headphones for a long time, if the headphones are worn for a long time and cause discomfort, you should go to the hospital in time.
