The fact that the hearing ability of a 21-year old is equivalent to that of an 80-year-old suggests that the damage caused by earbuds is likely to be related to nerve deafness. Nerve deafness is caused by damage to the hair cells of the inner ear or the auditory nerve, which typically occurs due to exposure to loud noise over time. Earbuds can generate sound levels that are high enough to cause permanent damage to the hair cells, leading to nerve deafness.
