DESCRIPTION
THE LEGACY OF QUALITY AND TRUST
Etymotic is credited with the invention of noise isolating in-ear earphones 30 years ago. The Etymotic design adopted balanced armature receivers and was used for auditory research and hearing tests. This served as the standard benchmark for high definition in-ear earphones. However, the Etymotic ER4 became the first noise-isolating, high fidelity in-ear earphones to be featuring this unique technology in a consumer earphone. That’s not all, these in-ear earphones are known to be the world leader for response accuracy when compared to other earphones. Therefore even after years, these reference-quality headphones are preferred by audiophiles, musicians and audio engineers.



EXPERIENCE NOISE ISOLATION LIKE NEVER BEFORE
These are the first earphones to provide a completely sealed in-ear fit. They offer 98% (35dB – 42dB) noise isolation which is best when compared to any earphones available in the market. One of the benefits of the best-in-class noise isolation is that you don’t have to listen to your music at extremely high volumes.



WITH STYLE, COMFORT, DURABILITY AND ASSURANCE
The body of the ER4 is designed with high-grade metal and has an anodized finish. They are built to offer a perfect and comfortable in-ear fit. The reinforced 5ft cables that come with this earphone are detachable and has 3.5 mm gold plated stereo jack as well as MMCX connectors. The Etymonic ER4 earphones feature a user-replaceable filter over the balanced armature drivers to protect it from ear wax. Moreover, these earphones have a 2-year replacement warranty.

RESULT OF YEARS RESEARCH AND DEVELOPMENT
Etymotic is known as the world leader in sound reproduction. They have unrivalled accuracy in frequency response and audio quality. The ER4 in-ear earphone has 92%+ response accuracy from 20Hz-16kHz. These are exclusive earphones to feature custom made balanced armature drivers with best-in-class output sensitivity.
