ER Series Custom Earplugs

Sensaphonics ER Series high fidelity earplugs were developed specifically as hearing protectors for musicians and production personnel who are exposed to unsafe sound levels. Unlike the muffled sound quality produced by over-the-counter earplugs, the ER Series is specifically designed with music in mind, making them perfect for concert-goers as well. ER Series earplugs give balanced sound reduction with very little disruption of frequency response. Definition of mid and high frequencies can be heard clearly for a safer, yet truly musical listening experience.

ER Series earplugs are different than any others on the American market. First, ear impressions are made by an audiologist. Then, custom molds are made of a unique, super soft silicone gel, so they can be worn for hours without discomfort. Finally, Etymotic filters are completely embedded in our ear molds, reducing the risk of the filter inadvertently falling out. Filters are offered in three levels of hearing protection.

  • ER-9 Nine decibels (dB) of noise reduction, perfect for everyday use
  • ER-15 Offers 15 dB of noise reduction for more intense environments like concerts
  • ER-25 A full 25 dB of filtering to counter prolonged exposure to high-noise conditions

    All three ER earplug filters are interchangeable. Earplugs may be ordered with or without a connecting cord.
