Etymotic Research Evo, In-Ear Monitors: 3 Drivers with True Low-End Sub Bass Earphones IEM (Etymotic EVO)
Etymotic History
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, the ER-4 (1991), which became the basis of all subsequent in-ear earphones and in-ear monitors worldwide. Thus creating an entire category of consumer electronics, and established these speakers as the gold standard for high definition in-ear earphones. 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 preservation are central to Etymotic’s mission. Etymotic’s products are used by university researchers, hearing practitioners, hearing-impaired consumers, professional and amateur musicians, and others who demand superior sound quality.
