Wind-Blox-Focus - Wind Noise Blockers for Bicycle Helmet - Noise Reduction Cover - Cycling Ear Warmers - Hearing Protection - Bike Helmet Accessories

Pas trop chaud, aucun vent dans les oreilles.

Positioning these in the right sport with just the Velcro doesn’t work very well. But I put 4 safety pins through the product and my helmet straps to fix it in place. Now they don’t slide down at all. Very comfortable and keep my ears warm. The product claims to not block out sound, but that’s just untrue. It blocks the wind sounds (which is good) but also deadens ambient noises (which is less good). You can hear about as well if you were wearing a hat over your ears. Personally, I think it’s fine, just don’t expect magical acoustic qualities.

These work as advertised. They muffle noise and insulate. They are comfortable. My only gripe is there are 4 layers of fabric, enough for sub zero temps, but too much if the mercury rises above 20° F. Would be nice if I could choose between 1 and 4 layers, depending on temperature.

As far a noise blocking goes, I'll have to take the developer at their word: its not a drastic reduction in wind noise, but mileage may vary depending on helmet style.I installed these on a Bern BMX style helmet more for the warmth they offered, and they do that reasonably well for winter riding.

Until now, I was unable to find a way to listen to a podcast while biking. If your bike at 15 mph, wind noise requires turning up headphones to a dangerous level. Even when I wore Apple AirPods Pro, there was a lot of wind noise.I tried Cat-Ears AirStreamz Cycling Wind Noise Reducer, and the wind noise was reduced but not eliminated.Wind Blox eliminated all wind noise. And even in 90° weather, they don’t get hot and sweaty. They seem to breathe well.If you are hoping to use these in the winter, they probably block the wind chill but they don’t have insulation to keep you warm. They are well vented.
