High-Fidelity Noise Isolating Earphones and Headsets

Etymotic Research invented in-ear earphone technology in 1984. Etymotic’s first insert earphones were designed for audiometric testing and auditory research. The first noise-isolating, high fidelity earphones to enter the consumer electronics market were the ER-4S and ER-4B in 1991, followed by the ER-4P in 1994. The ER-4 series is still winning premium awards almost two decades later.
