Etymotic
True to the ear, that is the meaning of Etymotic. Established in 1983, the brand is a technically driven research, development, and manufacturing company. Etymotic was founded to design research instruments that can accurately detect and assess hearing loss. With the knowledge gained from this, over the years, they have launched several noise-isolating hi-fi earphones on the market. Innovation, education and hearing conservation are at the heart of their manufacturing. This has made the brand a major player in the market for university researchers, hearing care professionals, hearing impaired, professional/amateur musicians and others who demand sound quality. If you choose Etymotic, then you are choosing high-quality IEMs (In Ear Monitors) that are in good taste.
