Etymotic Research - True to the Ears

Etymotic Research, Inc. is an engineering-driven research, development and manufacturing company. The name "Etymotic" (pronounced "et-im-oh-tik.") means "true to the ear." Mead Killion, Ph.D. founded Etymotic Research in 1983 to design products that accurately assess hearing, improve the lives of those with hearing loss, protect hearing, and enhance the listening experience of musicians and music lovers everywhere.

With deep roots in acoustic research and the hearing aid industry, Etymotic invented insert earphones in 1984. Etymotic’s original earphone design used balanced armature receivers, which established these speakers as the gold standard for high definition in-ear earphones. The first versions were used for diagnostic testing and precision auditory research (ER-1, 2, 3). Etymotic produced the first noise-isolating high-fidelity in-ear earphone, the ER-4 (1991), which became the basis of all subsequent in-ear earphones and in-ear monitors worldwide, and created an entire category of consumer electronics. The ER-4 earphones are still produced and channel-balanced to within 1 dB in Etymotic’s labs in the US.

Innovation, education and hearing conservation are central to Etymotic’s mission. Etymotic’s products are used by scientists, hearing practitioners, hearing-impaired consumers, professional and amateur musicians, and others who insist on superior sound quality. Audio engineers, audiologists and musicians working together have generated over 100 patents issued and pending. A number of Etymotic’s 60 employees are accomplished musicians. Etymotic Research is located in Elk Grove Village, Illinois.
