What makes Etymotic unique?
All of Etymotic's products are for the ear. We have developed everything from
high fidelity hearing aid integrated circuits to high fidelity hearing
protection. What makes us unique is our combination of expertise in
electroacoustics and hearing science. Scientists, engineers, and audiologists
working together have generated over 100 patents. The audiologists in
particular bring an in-depth knowledge of how people hear and how that will
affect earphone performance. Etymotic earphones are used in audiology clinics,
research laboratories, recording studios, onstage by performing artists and by
travelers. While Etymotic now has competitors in several product categories,
not one matches the performance of Etymotic products.
