ABOUT ET YMOTIC RESEARCH
Etymotic Research has spent over twenty-five years refining in-ear
technology for precision monitoring and critical listening. Etymotic's original
insert earphone design, developed for auditory research and clinical testing,
used balance armature receivers and established these speakers as the gold
standard for high-definition, in-ear earphones. ER•4 MicroPro earphones
were the first earphones commercialized using this technology and are
recognized as the world leader for response accuracy to which all other
earphones are compared.
Etymotic’s engineering team is led by founder Dr. Mead Killion, audiologist,
engineer, inventor and jazz musician. Etymotic’s audio engineers, musicians
and audiologists working together have generated over 100 patents issued
and pending.
Etymotic’s mission is to design products that measure, improve and protect
hearing. Etymotic’s products are used by musicians and others who insist on
superior sound quality. Etymotic means “true to the ear.”
