With extensive experience in acoustic research and the hearing aid industry, Etymotic is credited to be the inventor of in-ear earphones in 1984. The initial design of Etymotic earphones consisted of balanced armature drivers that acted as a standard for high-grade in-ear earphones. The first Etymotic earphones were utilised for diagnostic testing and precision auditory research: the ER-1, ER-2, and the ER-3. After this, they came up with noise-isolating high fidelity in-ear earphone ER-4 in 1991 that formed the basis for in-ears and resulted in the formation of a new category in consumer electronics.
The concepts of Innovation, Education and Hearing Conversation are at the centre of Etymotic's mission. Etymotic products aid various professionals and consumers including scientists, hearing practitioners, hearing-impaired and professional musicians. Their line-up of earphones like the Etymotic ER2XR, Etymotic ER2SE, Etymotic ER4XR, Etymotic ER3XR and Etymotic ER4 have won praises and recognition across the world. The Etymotic team has audio engineers, audiologists and musicians who have worked collectively to create more than 100 patents (issued and pending). Around 60 members of the Etymotic team are successful musicians.
