Product description

The ER4XR is Etymotic's flagship model: an ultra-precise in-ear monitor with a subtly enhanced low end for a slightly more musical sound. This ‘eXtended Response’ version of the ER4 series combines reference-class detail reproduction with a touch more body in the bass.

A single balanced armature driver in a CNC-machined aluminium housing delivers uncoloured, crystal-clear sound reproduction. The precision-tuned bass boost adds just that little bit of extra warmth and impact. Includes a robust, replaceable twisted cable and Etymotic's renowned passive isolation up to 42 dB.

The ER4XR is designed for discerning listeners who want an honest, balanced sound – but with a little more musical flair. The ideal choice for those who enjoy nuance and punch, without compromising on precision.
