Overview

Music lovers everywhere will appreciate exceptional sound quality and high fidelity.

Over 30 years ago, Etymotic invented noise-isolating, in-ear earphones. Etymotic’s original design, developed for auditory research and hearing testing, used balanced armature receivers and established these speakers as the gold standard for high-definition, in-ear earphones. ER4 earphones were the first high-fidelity, noise isolating in-ear earphones to use this technology in a consumer earphone, and are recognized as the world leader for response accuracy to which all other earphones are compared.

The ER4XR modal provides uncompromising accuracy in the midrange and high frequencies, but gives extra presence in the lower end.

For in-ear earphones that are best in class, order today.
