Etymotic (meaning: true to the ear) is an engineering-driven research, development and manufacturing company. Mead Killion, Ph.D. founded Etymotic along with Edwin DeVilbiss, MBA. in 1983 to design research instruments that accurately detect and assess hearing loss.

With deep roots in acoustic research and the hearing aid industry, Etymotic invented insert earphones in 1984. The first versions were used for diagnostic testing and precision auditory research (ER-1, 2, 3). Etymotic engineer, Steve Iseberg, produced the first noise-isolating high-fidelity in-ear earphone using balanced armature drivers.
