Developed as an update to Etymotic’s ER-4 flagship-line of earphones, the Etymotic ER4SR deliver reference-quality sound reproduction with high output levels for discerning sound engineers, audiophiles, and musicians who demand the highest fidelity.

The ER4SR feature balanced-armature technology, custom-tuned drivers, L-R channels matched within an industry-leading 1 dB, and 3-flange eartips which completely seal the ear to offer an impressive 98% of sound isolation. Their high sensitivity allows them to deliver a robust sound level up to 122 dB, making them well suited for portable media players with low output.

The ER4SR combine style and functionality with a sleek, anodized and laser-etched aluminum body, and a detachable, reinforced cable which is user-replaceable. They come with four pairs of 3-flange eartips, two pairs of foam eartips, a shirt clip, a filter removal tool &filters, and a zippered storage case.

The Etymotic Research ER4S stereo headphones feature an ultra-lightweight design, up to 42dB of external noise attenuation, and an enhanced output level for both the high and low frequency range, a combination that ensures clear, natural listening enjoyment at safe and moderate playback levels. These headphones have the most accurate frequency response for monitoring musical material, and are recommended for home stereo and computer use, while also satisfying the requirements of most portable devices.
