The QSA Bean
The BEAN is a high-fidelity personal sound amplifier that automatically amplifies only soft sounds; loud sounds pass through as though nothing is in the ear. The BEAN has a wider bandwidth than all hearing aids and can process high level inputs without distortion, resulting in excellent sound quality and clear music reproduction. There is high-frequency emphasis for soft sounds, which improves clarity for conversation, particularly in less-than-ideal listening environments.

Hear for a Lifetime®
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.
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.

Passive or Electronic Earplugs?
Use passive earplugs when you want to hear all sounds clearly, but quieter. When worn correctly, ETY•Plugs HD Safety Earplugs reduce all sounds the same amount so speech and environmental sounds are heard clearly. The amount of sound reduction provided by these earplugs is enough protection for most industrial uses.
Use HD-15 electronic earplugs for natural hearing when no noise is present and automatic protection when noise exceeds safe levels. Natural hearing is instantly restored when sound returns to safe levels.
