In-ear Invented here

Over 30 years ago, Etymotic invented noise-isolating, in-ear earphones. Etymotic’s original design, developed for auditory research and hearing testing, used balanced –armature receivers and established these speakers as the gold standard for high-definition, in-ear earphones. ER4 earphones were the first high-fidelity, noise isolating in-ear earphones to use this technology in a consumer earphone, and are recognized as the world leader for response accuracy to which all other earphones are compared. After more than 20 years, these reference-quality earphones are still the choice of serious sound engineers, audiophiles and musicians.

ER4XR is the earphone for music lovers and hi-fi enthusiasts who want uncompromising accuracy in the midrange and high frequencies, but appreciate a bit of extra presence in the lower end. Like the ER4SR, the ER4XR is built with precision machined, anodized and laser-etched aluminum bodies and features user-replaceable detachable cables. The ER4XR also incorporates the stringent channel-matching standard used in the ER4SR. The ER4XR is ideal for anyone looking for exceptional sound quality with just the right amount of low-end enhancement.
