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. See Non-Electronic Order Form 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) - See Order Form
$185.00/set includes a set filters (made from a silicone material) - See Order Form
($70/set for filters only) - Buy Online

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) - See Order Form
$185.00/set includes a set filters (made from a silicone material) - See Order Form

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) - See Order Form

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) - See Order Form
