NOISEFIGHTERS Gel Ear Pads for MSA Sordin/ Invisio T5/ TCI Liberator

Regular price $45.00 $42.00 Sale

  • New for 2018! First ever gel earmuff pads with relief cuts for glasses to pass through without breaking the seal and causing headaches. Best results with straight-style glasses arms, and our super-soft silicone gel produces an amazing seal with other types of glasses arms.
  • Our unique horseshoe-ring shaped double-hump front face and 1/4" inch of silicone gel provide significantly better softness and sealing vs. competitors' pads.
  • When headset is lowered as much as possible, glasses arms can be dropped into relief cuts and will sit in a protected channel just above the ear. Using the relief cuts is completely optional. Our gel pads also work like normal without glasses.
  • Use of super-premium acoustic memory foam and a closed head seal leads to impressively better sound deadening that is immediately noticeable to even the most casual user.
  • Made in the USA by a USMC veteran-owned company and designed for use in any climate. Polyurethane outer skin is UV-resistant, waterproof, and much longer-lasting than vinyl used on cheap pads. These gel pads are tough.

SightLines™ was launched on Kickstarter in November of 2017 and successfully brought to market through the generous pledges of hundreds of people from around the world. We want to thank them again for their support.


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

Neal Brace, SightLines inventor and owner of Noisefighters, is a U.S. Marine Corps combat veteran (OIF + OEF) who recognized this issue while at the shooting range. He identified that the problems caused by headsets and glasses interference were more than an annoyance: they were a significant hindrance to one's ability to concentrate on the task at hand. Instead of simply putting up with the problems listed above, he decided to solve them.


By adding a recessed channel, or relief cut, at the top of the pad 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. Our headset pads replace your existing ones and install in seconds.

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 pad 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 pads 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 ear pads again.

The only change you'll need to make when wearing a headset with SightLines is to first lower your headset as much as is comfortable, slide your eyewear above the pads, and then pull the arms down into the relief cuts. The arms will rest 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 after just a few moments. These pads are fully compatible with prescription eyewear, including multifocal lenses.

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 hearing protection issue: it is extremely detrimental to proper monitoring of audio levels and radio traffic, which is important to pilots / soldiers and Marines / SWAT officers / etc. Again, we believe SightLines solves this completely by keeping the head seal closed when eyewear is inserted correctly into the relief channels.


SightLines pads are manufactured with only premium components. They are designed to survive in nearly every environment on earth. As military veterans, we 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 antifungal properties, and does not absorb moisture and quickly degrade like cheaper materials.

Our product should last for several years of normal use instead of degrading quickly like faux leather or vinyl pads. Be sure to regularly clean the outer surface of our pads with soapy water as necessary but do not submerge.


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 veteran owned company.
