Filtered Plugs
This design replicates the natural response of the ear canal so that the sound heard is the same quality as the original, just a bit quieter. The differences in buttons are listed below. Contact Us to purchase any of the following products.

ER-9
The ER-9 has reduced diaphragm stiffness for less attenuation (reduction).
- Reduced attenuation (better audibility) then the ER-15
- For use when a small amount of protection is adequate
- Good frequency response
- 9dB attenuation through 2 kHz
- Available colors - Beige or Brown
- Style - compact
Cost:
- $130.00/set includes a set of filters (made from a polyurethane material)
- $185.00/set includes a set of filters (made from a silicone material)
($70/set for filters only)
ER-15
The ER-15 has a diaphragm which functions as an acoustical compliance, as well as an acoustical mass. This results in a smooth and flat attenuation (reduction).
- Practically perfect frequency response
- Provides the same attenuation at all frequencies
- Minimum occlusion effect with deeply-sealed custom earmolds
- 15dB attenuation
- Available colors - Beige or Brown
Cost:
- $130.00/set includes a set of filters (made from a polyurethane material)
- $185.00/set includes a set of filters (made from a silicone material)
($70/set for filters only)
ER-15SP
The ER-15SP (sports Plug) response is similar to the ER-15, but the 6kHz side branch resonance (which smoothes the ER-15 response above 3kHz) was sacrificed in order to provide the smallest possible size.
- Smaller then the ER-15
- 15dB attenuation
- Used by athletes and others in high noise environments where hearing signals and sounds are important
- Available colors - Orange
- Styles - compact
Cost:
- $130.00/set includes a set of filters (made from a polyurethane material)
- $185.00/set includes a set filters (made from a silicone material)
($70/set for filters only)
ER-25
The ER-25 has an increased diaphragm stiffness and an acoustical mass channel molded into the button for more attenuation (reduction).
- Increased attenuation good frequency response
- Used by drummers and others exposed to high sound levels
- 25dB attenuation
- Available colors - Beige or Brown
- Styles - Original or Compact
Cost:
- $130.00/set includes a set of filters (made from a polyurethane material)
- $185.00/set includes a set of filters (made from a silicone material)
($70/set for filters only)
