About Etymotic

Etymotic Research has spent over twenty-five years refining
in-ear technology for precision monitoring and critical listening.
The first in-ear earphones were invented by Etymotic in 1984 for
clinical audiometry and auditory research, and later converted to
the first high-fidelity, noise-isolating earphones, the ER-4s
in 1991.

Etymotic’s engineering team is led by founder Dr. Mead Killion,
audiologist, engineer, inventor and jazz musician. Etymotic’s audio
engineers, musicians and audiologists working together have
generated over 100 patents issued and pending.

Etymotic’s mission is to design products that measure, improve
and protect hearing. Etymotic’s products are used by musicians
and others who insist on superior sound quality. Etymotic means
“true to the ear.”
