AirStreamz Slim™ Cycling Wind Noise Reducer

I have several friends who have used Cat-Ears for quite some time and they always went on about how well they work. I have been happy for them but always thought they looked out of place. I reckon I was too judgemental.After coming off of a long ride into unceasing headwinds and ringing ears, I decided to give this product a try.Wow. I wish I had been less judgy and purchased them sooner. They work a treat! Not only do my ears like not having the wind's roar, but I can hear traffic much better and communicate better with my riding mates which makes for a better experience on the bike all the way around.

I live in the Midwest where it's very windy. It doesn't cut out the noise completely but definitely makes it easier to hear people especially in headwinds.

This product works pretty well. It's easy to install and use, and the wind noise is in a comfortable range now. The product reduces wind noise noticeably, but not the majority.I started riding a fast pedal-assist electric bike for my commute a few months ago and noticed the large amount of wind noise going ~28 MPH. I started to get concerned because it's easy to sustain that speed for a long time and I realized I might be risking loss of hearing. So I did a little internet research to learn that wind noise on a bike is probably above 80-90 dB above 20 MPH.I bought the Cat-Ears AirStreamz Slim and installed one side in under a minute and pocketed the other one on my first ride to hear the difference, which was noticeable. I guessed it dropped the perceived noise level by about a half--a purely subjective measurement, of course. The graph shown as a product image shows about -12 dbA attenuation at 30 MPH for AirStreamz (-10 dBA is usually perceived by humans as half). With both of the Cat-Ears on my helmet the noise feels much more like when I was riding at about ~15-20 MPH, my non-electric bike commute speed; I can live with that.I'd give the product 4.5 stars if I could: the pair works a little bit less effectively than I hoped (so perhaps I'll later try the standard / non-"slim" product), but it's a good value for a set-and-forget solution and gets me most of what I need.

I ordered these hoping they would help the wind noise while biking with my hearing aids. While they help some, they don't eliminate the wind noise. One note here. The. instructions say to wear any glasses outside helmet straps as wearing inside the straps creates a gap to allow more wind noise. I found this is true and it makes sense but my ear pieces don't sit well outside the straps, something that is not the fault of the Cat Ears. Also I usually use a custom program on my hearing aids to cut more noise and I did not use it in order to test these. Bottom line: yes, they cut down the wind noise but don't eliminate it. For the price, I think it's a good value as they do help. Also , they are comfortable to wear.

I really wanted these to work. Honestly. Instead, they’re just a waste of money that make you look (at best) like an Elvis impersonator.I feel like I could write a lot about why these didn’t work with my specific helmet but… ultimately? There’s not much point. If your helmet has straps that are anchored in the middle of the helmet shell (as is the case with the POC Octal MIPS)? The straps will never sit close enough to your head in front of your ears for these to do anything. Maybe the original ‘furry’ cat ears work better. I don’t know. But I followed the instructions and tried fitting the slims in both orientations. The difference in wind noise w/ and w/o (if there is one at all) is so subtle that it’s not worth the goofy looks.

Ordering this on a whim, I’ll admit I did not have high expectations for this product when I ordered it. Bottom line it works, follow the instructions and it will reduce the wind buffeting and turbulence in your ears. On a 20 mile 18mph road ride with cross winds it did reduce the noise caused by the turbulence in the ears. Turn your head sideways or tilt head down to sprint lets the wind back in. No surprise there. You do need to have your straps tight enough so that the Catears are snugly against your cheeks. If not, air gets under the fur causing turbulence in the ears and defeats the purpose. If you have a crosswind, you will hear turbulence in the ear on the windward side as the air will not be deflected but the Catears. Surprising how much sound it removes while headed into the wind or on a windless day. It's not completely quiet, but it does as the company promotes-significantly reduces the in ear turbulence/noise in the ear. It did seem to make the cars and other cyclists sounds louder the first time I tried it. I heard a cyclist slip into my draft before I saw his shadow. In the wind, I normally would not have been able to tell. Surprisingly good results - worth a try. Yes; your shadow makes you look like Elvis in a helmet.

Have used them for a few weeks. Anecdotally, I feel like they reduce the wind noise by ~50-60% depending on the wind direction and how fast you're going. Hard to judge how well they work until you take them off in midst of a ride and/or ride with just one, then it's easy to hear the difference. I have the 'slim' version, others may be different. Easy to install, they look a little goofy but not too bad. I wear prescription glasses and they're okay with them, as are regular sunglasses. I worried about how they would absorb my sweat on hot days and if they would become saturated and ineffective but they worked well throughout our 90-95 degree summer days. Worth a try in my opinion.
