SAFE LISTENING FOR MUSICIANS

Musicians practice and perform in varied settings. What they have in common is the risk of permanent hearing damage from the cumulative effects of overexposure to loud sound over a lifetime. Custom and ready-fit earplugs are designed to provide accurate sound reproduction; sound is the same as the original, just quieter—and safer.
Etymotic In-Ear Monitors
ER•4 earphones, the world’s first noise-isolating, high-fidelity in-ear earphones, were developed in 1991. ER•4 circuitry has been emulated in custom monitors for over two decades. ER•4s are used by many performing musicians. Since all Etymotic earphones are highly accurate, musicians on a budget can use any earphones as in-ear monitors.
