Impact Sport Electronic Earmuffs:

As safety on the range and in the field is most important, Impact Sport keeps wearers both protected from hazardous noise and connected to their environment. Impact Sport employs built-in directional microphones that amplify range commands and other ambient sounds to a safe 82 dB, providing more natural listening and enhances communication. For protection, Impact Sport actively listens and automatically shuts off amplification when ambient sound reaches 82 dB, effectively blocking out hazardous noise.


  • Amplifies ambient sound to safe 82 dB – response technology revert to passive hearing protector when noise reaches 82 dB
  • Allows wearers to hear important communications, including other shooters and environmental sounds
  • Directionally placed stereo microphones amplify and enhance sound for more natural hearing
  • Non-deforming outer headband withstands rough treatment in the toughest workplaces
  • Low-profile design with cut-out allows for full clearance of firearm stock, eliminating interference while shooting
  • Features Bilsom Technology’s patented Air Flow Control? technology for optimal attenuation across all frequencies
  • Snap-in ear cushions make replacement quick and easy
  • AUX input allows connection to external MP3 players or other audio devices for additional listening off the field

SightLines Compatible Headsets:


Why use SightLines Ear Cushions?

Earmuffs that use traditional cushions rely on the softness of the ear cushion to conform to the shape of the eyewear stems. However, whenever eyewear is inserted, even the softest cushions unevenly distribute pressure around the ear, cause hot spots which then lead to headaches, and allow unwanted noise through the broken head seal.

By adding a recessed channel, or relief cut, at the top of the cushion for eyewear to slide along, the head seal can remain intact instead of being forced open when eyewear is inserted. SightLines is an extremely simple and inexpensive solution. SightLines headset cushions replace your existing ones and install in seconds.

The only change you'll need to make when wearing a headset with SightLines is to first slide your eyewear above the cushions and then move them down into the recessed upper channel and onto the shelf. The shelf is less than one pinky finger's thickness above the location where glasses normally rest, and it feels completely natural for eyewear to sit at this location. These cushions are fully compatible with prescription eyewear, including multi-focal lenses.

Eyewear no longer causes hot spots around the ears. In addition, the unique horseshoe ring design and use of silicone gel and memory foam softens the cushion so much that compression is significantly reduced, pressure is better equalized across a larger surface area, and eyewear won't sit crookedly. It's like wearing pillows on your head. Our cushions are also quite roomy, so ears won't feel cramped. You can wear them all day with or without eyewear, with no change in comfort. You won't ever want to wear normal headset cushions again.

Government testing has shown a 1-10dB decrease in sound deadening when eyewear breaks the head seal on traditional ear cushions. This is a serious safety issue as a 3 dB increase represents a doubling of sound intensity. We believe SightLines solves this completely by keeping the head seal closed when eyewear is inserted correctly.

A broken head seal permits significantly more noise into the headset, and this isn't just a safety issue: it is detrimental to proper monitoring for audio professionals and it's annoying for anyone who wants to keep undesirable noise out when wearing eyewear (like an airline passenger using noise-cancelling headphones or a pilot trying to monitor incoming traffic). Again, we believe SightLines solves this completely by keeping the head seal closed when eyewear is inserted correctly.


Materials and Durability:

SightLines cushions are manufactured with only premium components. They are designed to survive in nearly every environment on earth. SightLines was designed by military veterans, who understand that gear dependability is crucial.

Internally, both silicone gel and sound-deadening memory foam provide the ultimate in softness. The silicone gel's flexibility is amazingly similar from -100F to +300F (-70C to 150C). The sound-deadening memory foam meets FAR 25.853 for U.S. aviation use.

Externally, an ultra-thin sheet of rugged polyurethane provides a supple outer skin. The polymer skin is resistant to UV rays, has anti-fungal properties, and does not absorb moisture and quickly degrade like cheaper materials.

SightLines should last for several years of normal use instead of degrading quickly like faux leather or vinyl pads. Be sure to hand wash our cushions with soap and water as necessary. It is not recommended that you submerge the headset cushions in water.


SightLines are made in the U.S.A. by a factory supplier with over 40 years of experience making ear pads. Noisefighters is a service-disabled U.S. veteran owned company.

    Great Combination

    Posted by Christopher Marmon on Apr 13th 2022

    I bought these for my son so we can communicate at the gun range. These are great budget ear pro and the noisefighter gel cups are so comfortable. I would highly recommend. I saw a video of a lady opening up the ear pro and pack it with foam from an old yoga mat to make the ear pro block out the loud noises a little better. Those noisefighter gel cups are so worth the money.

    Ear Protection

    Posted by VideoGeek on Jul 1st 2021

    These are a nice fit and they function as advertised and it's hard to beat their price. I am very protective of my hearing and although I would prefer a headset that provides a higher NRR, I do have them for the wife and I.

    Attached the new Earpads and mounted the Headset to my Helmet for work! Works amazingly and the earcups feel/seal way better than the OEM ones!
