Etymotic
Etymotic is an engineering-driven research, development and manufacturing company. Founded in 1983 with deep roots in acoustic research and the hearing aid industry. Etymotic invented the first earphones, which became the basis of all subsequent earphones and in-ear monitors worldwide, and created an entire category of consumer electronics. The meaning of the word Etymotic is true to the ear.
Innovation, education and hearing conservation are central to Etymotic’s mission, with their products being used by scientists, hearing practitioners, hearing-impaired consumers, professional and amateur musicians, and those who insist on superior sound quality.
ER4SR is Etymotic’s reference hi-fidelity in-ear monitor, for those who demand nothing less than the highest reproduction accuracy.
ER4XR is Etymotic’s in-ear monitor for those who demand nothing less than the highest reproduction accuracy in the midrange and treble frequencies, but prefer a tastefully added bass presence.
