Earbuds only do more damage when when you are trying to overpower ambient noise. As Ambiguity mentioned Shure and others make earbuds that come with several fittings that help you first isolate yourself from ambient noise.

(1) The ear "prefers" mid-high to high frequencies over low frequencies.
(2) The ear is not suited to long intervals of high amplitude.
(3) The ear prefers harmonic to inharmonic sounds.
(4) And the ear prefers sustained sounds over periodic sounds.
(1) High frequencies exercise the flexibility of the ear's cilia (the little hairs that vibrate within the ear canal. Constant low frequencies tend to atrophy the ear's ability to hear high frequency sounds. High frequencies coupled with low frequencies tend to mitigate, to some extent, the negative effect of low frequencies.

Ear infections are caused by trapped viruses or bacteria and swelling developing behind the eardrum (tympanic membrane) when the child has an upper respiratory infection. The eustachian tube opens into the middle ear, behind the eardrum. In children, this eustachian tube is smaller and more horizontal than that of an adult, and these factors cause the tube to become closed when swollen. The fluid is trapped in the middle ear because the eustachian tube is closed. Viruses and bacteria then multiply in this trapped area, resulting in an infected eardrum.
