Developed as an update to Etymotic’s ER-4 flagship-line of earphones, the Etymotic ER4XR deliver reference-quality sound reproduction with a modest bass boost and high output levels for discerning sound engineers, audiophiles, and musicians who demand the highest fidelity.
The ER4XR 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 ER4XR 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.
