Our products have been road tested and are recommended by major cycling publications.
We have sold thousands of Cat-Ears since we opened in 2012... our patented* approach has been
proven to be the most effective solution for reducing Ear-Wind Noise. Aero-acoustically designed and
tested, Cat-Ears are made from soft, sound permeable materials that dampen, quiet and deflect
without blocking the sounds you want and need to hear for safe cycling.
- Hear cyclists about to overtake you - Hear approaching cars and trucks
"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
"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
"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
"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 will give
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 significant" Translation 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 that is commonly used in the recording
industry to reduce wind noise. The 'ears' are fastened onto helmet straps with a Velcro..." Krista Carlson - Urban Velo
Soft material works by absorbing turbulence energy and the efficiency is very high… since it absorbs energy, it contributes no noise itself.

"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

Cycling Industry Reviews are Unanimous... Cat-Ears Significantly Reduce Wind Noise!
Our Classics Products Provide Unsurpassed Wind Noise Reduction
Less Wind Noise (-8dB / -12 dB) + Warmth
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.
Cat-Ears don't block surrounding sounds... so they don't interfere with spacial orientation / situational awareness.
"Cat-Ears don't restrict hearing while others I've tried do..." (PF - Adventure Cycling Association)
Taking a cue from nature, we use soft sound permeable materials to significantly
reduce wind noise... similar to how audio experts reduce microphone wind noise.

Unsurpassed Wind Noise Reduction for Serious Cyclists
Wind Noise (perceived and annoyance) varies considerably from cyclist to cyclist. It can, however,
easily exceed ~70** dB at moderate cycling speeds.
(*a threshold shift >40 dB is considered impairment)
** Wind Noise can mask sounds like approaching vehicles (60-80 dB depending on speed / road surface) at similar frequencies (Hz). In addition,
levels of 55 decibels outdoors and 45 decibels indoors are identified as requisite for preventing activity interference and annoyance (EPA, 1974)
The Choice of Serious Cyclists:
=> Unsurpassed Wind Noise Reduction
=> Dampen, Quiet and Deflect the Wind
=> Aerodynamic Design (very lightweight)
=> Acoustically Transparent (not blocking)
=> Moisture Wicking / Breathable Materials
=> Optimize the Sound to Wind Noise Ratio
=> Proven (soft pile material) Fluid Dynamics
Testing / Consulting / Evaluation
=> *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. Goto, Aerodynamic Noise Reduction by Pile / Fur Fabrics, 2010)
=> Turbulent (wind) velocity fluctuations, converted to pressure fluctuations, are a primary source of annoying ear
wind noise. And Turbulence is strongest at the point at which eddies shed from the downwind side of an obstacle.

Cat-Ears are based on Proven Wind (Induced) Noise Reduction Techniques... visit our 'How They Work' page
The objective is to reduce the effect(s) of the wind - without blocking sound waves
Wind typically flows turbulently into your ears
With Cat-Ears, Wind flows quietly over your ears
