Etymotic Research Inc makes earphones. Their mission is innovation, education, and hearing conservation. This
engineering company does research, designs develops, and manufactures earphones. Etymotic means “true to the ear”.
The company was established by Mead Killion in 1983 to design products that could protect hearing and offer solutions to hearing impaired. They also offer products that improve the listening experience of music lovers and musicians.
Thanks to deep roots in the acoustic research and hearing aid industry Etymotic invented insert earphones in 1984. The original earphones used balanced armature receivers which became the gold standard for High Definition in-ear headphones.

The initial versions were used for precision auditory research (ER-1, 2, 3) and diagnostic testing. The company 
produced its first noise-isolating Hi-Fi in-ear earphones (ER-4). These became the foundation for the subsequent in-ear models worldwide.
This prototype also created a new category of consumer electronics. The ER-4 first produced in 1991 are still produced and are channel balanced to 1 dB in the company’s lab in the USA. Etymotic products are used by hearing-impaired people, audiologists, scientists, professional and amateur musicians.
Audiologists, audio engineers and musicians have worked together to generate over 100 patents – pending and issued. And many of Etymotic’s sixty employees are accomplished musicians. The company is situated in Illinois.
The 1980s saw a revolution in electronics as they become compact and High Fidelity. The increase in telecommunication brought increased access to music and its appreciation. This gave rise to a market related to audio-visual products. There was a boom in the type of cassette players, radio, Walkman, CDs, and cellphones.
An advancement in AV technology gave a boost to the in-ear technologies too. From hearing aids these devices were transitioning to entertainment. Slowly earphones have become a staple for everyone who carries a mobile phone or loves music.

Key Features of Etymotic Earphones
These earphones prevent hearing damage by risks of using various types of earphones.
Noise is omnipresent – In today’s tech-connected world everyone lives in a High Definition – this includes sound. People listen to Blu-ray, 3D movies, surround-sound, etc. We use TV, gaming consoles, tech toys, play in bands, etc. Sound levels exceed safe limits. The users don’t know how much noise is too much noise. The louder the noise the lesser time you should listen. Audio of up to 85 dB for 8 hours per day or 40 hours per week is safe. Etymotic earphones keep the noise within safe limits for prolongs listening bliss.
Active noise-cancellation feature on the earphones detect and cancel low-frequency sounds by reversing the phase of the signal.
Noise isolation feature offers hearing protection by blocking outside noise. The in-ear devices seal the ears and offer twice as much noise insolation as ANC devices.
Volume control – The common reason people turn up the volume is to cut out the background noise. As the noise-isolation headphones seal the ears the background noise is eliminated. Due to this feature, people keep the volume lowered at safe levels.
Safe for children – As children’s ears are delicate and ears not only help listen but balance. It is imperative parents chose the children’s earphones carefully.
High definition and excellent sound quality – Etymotic earphones have a smooth frequency response. The reduced sensitivity means that the listener experiences sound, games, music, etc. as they are intended.
