Etymotic ER4SR IEM
From the Leader in Noise-Isolating In-Ear Monitors
A classic IEM that’s been refined over decades, the Etymotic ER4 gets its latest update in the ER4SR: a model that delivers accurate, reference-quality sound with excellent noise isolation—up to 42 dB of reduction, to be exact. The ER4SR features precision-matched and custom-tuned balanced armature drivers inside sleek anodized aluminum housings, along with a detachable 5-foot-long cable that ends in a 3.5-millimeter gold-plated stereo plug. Plus, its design completely seals the ear to block out the outside world. Improving upon the ER4S’s tonal accuracy, the ER4SR IEM is ideal for engineers, audiophiles, and discerning music lovers.
