Etymotic Research Custom Hearing Protection

Etymotic Research Custom Hearing Protection

The custom made ER-Series hearing protectors reduce all sounds equally, so it’s just like turning down the volume without sacrificing any of the definition of what you want and need to hear. They produce the flattest level attenuating characteristics of any hearing protector available over a frequency range of 125 – 8000Hz. As a result of the flat attenuation, the sound keeps its natural wave without any distortion.

Custom-moulded ER Hearing Protectors:

  • use a genuine ER- broadband filter without distortion
  • provide a 15dB flat attenuation as a standard
  • offer interchangable attenuation, 9dB or 25dB, which can be supplied as agreed or can be purchased in addition to the ER-15dB 


Custom-moulded ER Hearing Protectors are made from a medical grade silicone for comfort and come with a 2 years manufacturer’s warranty against fit and sound seal and workmanship.

Please note: These are custom ear plugs and will require physical ear impressions of your ears; this is carried out during the initial consultation. Once done, we can then fit you with your own set ER-15dB in about 6-7 working days.
