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.
Etymotic designs products to measure, improve and protect hearing, and enhance the listening experience of music lovers everywhere. Audio engineers, musicians and audiologists at Etymotic have generated over 100 patents issued and pending.
ER4XR is the earphone for music lovers and hi-fi enthusiasts who want uncompromising accuracy in the mid-range and high frequencies, but appreciate a bit of extra presence in the lower end.
The ER4XR incorporates the stringent channel matching standard used in the ER4SR and is built with precision machined, anodized and laser-etched aluminum bodies, and features user-replaceable detachable cables.
The ER4XR is ideal for anyone looking for exceptional sound quality with just the right amount of low-end enhancement.
User Detachable CablesTo detach the cables, pull the cable connector away from the earphone body. Pull straight out-DO NOT TWIST. To attach the cables, align the key tab on the cable connector with the notch in the body of the earphone. Press together until it snaps in place. |
Changing the FiltersEtymotic earphones have special filters that smooth the frequency response and prevent earwax from entering the earphones. The filters are located at the end of the earphone and are visible when the eartip is removed. When a filter becomes clogged it should be replaced. Filters should be changed when output decreases or sound quality declines. |
