ER4's - as reference monitors, in the studio, or live performance make me feel completely connected to the sounds! They sound 'AS THINGS SOUND' - accurate, transparent and have plenty of presence and punch...plus STELLAR isolation! Also, the 'ears behind the ears' at Etymotic are as GENUINE as the sound they produce!! Dan Wojciechowski - Drummer, Peter Frampton's band
ER4 earphones were the first high-fidelity, noise isolating in-ear earphones to use this technology in a consumer earphone, and are recognized as a world leader for response accuracy. After more than 20 years, these reference-quality earphones are still the choice of serious sound engineers, audiophiles and musicians.
ER4SR is Etymotic’s new reference standard hi-fidelity earphone, for those who demand nothing less than the highest fidelity. The next generation of our long revered flagship earphone, the ER4S, the ER4SR delivers increased accuracy with greater sound output, or sensitivity. The new ER4SR incorporates significant cosmetic and functional improvements, from a sleek, anodized and laser-etched aluminum body to the reinforced, user-replaceable detachable cable.
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.
Both ER4 models are available for purchase in-store or through our online store.
