Musician earplugs are ideal for professional musicians, concert goers, or sound technicians. With three interchangeable filter sizes available (shown in the chart below) musicians have a wide variety of applications available. Each filter is designed for specific frequency attenuation (volume reduction) based on the instruments or environment. Call us if you have any additional questions and we'll let you know which filter will work best for you.


What Makes Musicians Earplugs High Fidelity?

The musician earplug filters, or buttons, have a diaphragm which functions as an acoustic compliance, while the volume of air in the sound bore of the custom earmold acts as an acoustic mass. The combination of the two produces a resonance at approximately 2700 Hz (as in the normal ear), which results in smooth, flat attenuation.

  • ER-9 Provides flat 9 dB sound reduction through the mid range and 15 dB in the highs
  • ER-15 Provides uniform 15 dB sound reduction across frequencies
  • ER-25 Provides 25 dB relatively flat sound reduction across frequencies

Musician Earplugs NRR of -9 dB to -25 dB
