Product description

The ER4SR is Etymotic's ultimate single-driver in-ear model, designed for those who refuse to compromise on sound accuracy. With a completely flat, reference-class response, this in-ear monitor offers an extremely detailed and transparent listening experience.

Made from CNC-milled anodised aluminium with very tight tolerances, and equipped with a single Balanced Armature driver. This combination guarantees maximum precision without additional complexity, while the compact aluminium housing is comfortable and durable. The robust, replaceable twisted cable increases the service life.

Etymotic's world-renowned passive isolation provides 35-42 dB of attenuation, effectively blocking out distracting ambient noise. This makes the ER4SR ideal for professionals and discerning listeners who want to hear unfiltered, accurate sound in any environment.
