"Cat-Ears work, in fact, dramatically well. (They) deflect and dampen wind noise... while still letting other sounds like
  traffic or conversation pass (through).  With Cat-Ears, I found I was enjoying rides more, simply because I could hear
  more of what I wanted to (hear), and less of what I didn’t." Joe Lindsey -  Bicycling Magazine (click to read articles)

"I cannot say enough good things about this product. Having said that, I will now attempt to summarize my elation at an
 ingenious solution to a heretofore unsolved dilemma. Wind Noise can inhibit one’s ability to distinguish traffic noise, often
 a first line of defense, particularly in an urban setting. Cat Ears don't restrict hearing while others I've tried do. Anytime that
 sightlines are restricted, audio cues can be the only warning to exercise caution." P. Finley - Adventure Cycling Association

"Cat-Ears work well at reducing wind noise, particularly at higher speeds.  Allowing improved awareness of surrounding
  traffic (and racers)” - “I heard little more than tires, gears, and birds on my am ride.” J. Huang, Tech Editor at BikeRadar 
Soft material works by absorbing turbulence energy and the efficiency is very high… since it absorbs energy, it contributes no noise itself.

Listen to the Cat-Ears Product Review
"I had the opportunity to try your products this weekend... About halfway through the ride, I suddenly realized that I could
hear EVERYTHING that was being said in my group of 5 riders! I could still hear some wind noise, but I was very impressed with
the fact that I could hear riders several bike lengths in front of me."  League (of American Bicyclists) Cycling Instructor/Coach

The solution to reduce Wind Noise while cycling
Our products are designed, tested, and made in Boulder, Colorado... allowing us to maintain the highest quality control thanks to the development of proprietary Six Sigma manufacturing processes. It also allows us to rapidly prototype design concepts that would be difficult, if at all possible, if we had our products manufactured overseas. The materials we use are also made in the USA.

U.S. Utility Pat. No. 9,078,482 - 'Sound Permeable Wind Noise Reduction Device'

"Wrap this half-inch pile of faux fur around your front helmet strap to reduce wind noise in your ears by 40 to 60 percent,
  so you can more easily hear cars coming and friends talking... For races, pick up some lower-profile Cat Ear Pros."
  Erin Beresini, (8 Triathlon Essentials for Racing Fast... Dominate the road with the help of this gear)  Outside Magazine

"With these (Cat-Ears)... now you can actually hear more of what's coming up behind you... if you are in a road race or
 mountain bike cross country race, you'll be able to better hear your opponent attacking you from behind and this gives
 you an advantage over the other racers." From the review by Robert Sandoval on Bike Sport Radio (Los Angeles, California)

"We tested various models for many months... yes, they work! Obviously they don't fully eliminate wind noise. However,
  the reduction proves significantTranslation from the review by Amal Donnet (correspondant-testeur) at Velo de Route (France)

"Do they work? Yes, as advertised, Cat-Ears reduce wind noise. We logged a handful of rides wearing the Classics Pro
 model and found it easier to hear traffic and carry on conversations with our riding friends"  J. Sumner - Road Bike Review

"Getting around by bike is enjoyed by all the senses... the simple and ingenious Cat-Ears allow us to hear what is really
  important... without the distortion of the air (~ wind noise)...Translation from the review by Manel Ibars at Bicimag (Spain)

"With an effect similar to windshields that journalists put on microphones outside... Wind noise is not completely removed,
  but significantly attenuated... the other observation is that I feel like I am riding slower."  J. Fess - Bikin' Valais (Switzerland)

"Cat-Ears are made of acrylic faux fur material and mimic actual cat’s ears, a method commonly used in the recording
  industry to reduce wind noise. The 'ears' are fastened onto helmet straps with a Velcro..."   Krista Carlson - Urban Velo

Cat-Ears don't block surrounding sounds... so they don't interfere with spatial orientation / situational awareness.

 "Cat-Ears don't restrict hearing while others I've tried do..." (PF - Adventure Cycling Association)
=>  *The (wind) noise-reducing mechanism is such that the fur makes the shear layer gentle and causes the maximum
      turbulent region to move far away (M. Nishimura and T. GotoAerodynamic Noise Reduction by Pile / Fur Fabrics, 2010)
Wind Noise without Cat-Ears (~15 MPH) ===>

Wind Noise with Cat-Ears (~15 MPH) =====>

Cat-Ears are acoustically 
transparent so they don't interfere
 with spectral cues / sound localization
=>  Turbulent (wind) velocity fluctuations, converted to pressure fluctuations, are a primary source of ear-wind noise.  
=>  We use sound permeable materials to reduce wind noise... similar to how audio experts reduce mic wind noise.​
The Worlds Best Selling, Safest, and Most Effective

World's Best Selling / Proven Most Effective
Our products have been extensively tested and are recommended by respected cycling publications.
We have sold thousands of Cat-Ears since opening in 2012. Our patent protected approach has been
proven to be the most effective solution for reducing Ear-Wind Noise. Aero-acoustically designed, and
tested by experts, Cat-Ears are made from sound permeable materials that reduce the turbulent air
 flow near your ears... without blocking the sounds you want and need to hear for safe cycling.
