Cat-Ears are the best selling and most effective Wind Noise* reduction products of their kind - see comparative analysis. They have been independently tested / recommended by Bicycling, Bike Radar, Road Bike Review, and Outside Magazines.
The longer (4") AirStreamz XL (HA**), based on PileTech materials engineering, are recommended for Casual to Competitive Cyclists.
Developed through aero-acoustic research, AirStreamz are made from acoustic pile materials that dampen / dissipate / deflect oncoming wind and reduce the intensity of noise producing turbulence.
Cat-Ears products are sound permeable for safe road cycling. "Wind Noise can inhibit one's ability to distinguish traffic noise, often a first line of defense in an urban setting. Cat-Ears don't restrict hearing while others I've tried do." - Adventure Cycling Association. Our materials have been tested for effectiveness and transparency at Antioch University.
*Wind Noise is a complex phenomenon spanning aerodynamics, acoustics, and the physiology of human hearing. The amount experienced depends on factors like: 1) speed, 2) riding position, 3) head shape, 4) turbulence, and so on. With Cat-Ears, wind noise levels are reduced by 14-16 dBA between 20 and 20k Hz. This is a reduction in sound pressure level of ~75%. But microphones and ears behave differently. And while the amount of perceived wind noise reduction can vary, we stand behind our products as the most effective devices of their kind on the market.
"Cat-Ears work dramatically well. I found I was enjoying rides more, simply because I could hear more of what I wanted to, and less of what I didn't." - Bicycling
**Reduces above / behind the ear wind flow - suggested for many BTE hearing aids.
