They do what they say, reduce the wind. I lifted them away from my ear and I could definitely tell the difference. I could hear my music more easily and hear my friends conversation. Obviously if there is a cross wind they are not effective. I wear my strap pretty tight, so they are a little snug fit, and slightly uncomfortable. However, you get used to it. My friend wears his straps more lose but he tells me that the product still works well. Overall very happy with them. — Jane Dean

I wear hearing aids that are set up to alleviate moderate hearing loss. Wind noise is always bothersome to the point where walking into a headwind is unpleasant. I installed this product as directed. This was a very easy process. I just had to lengthen the head strap that lies in front of my ears. This led to minor adjustments to the straps behind my ears and under my chin. From start to finish installing the two wind-blockers took less than four or five minutes. Comfort was fine too. After two or three minutes I didn’t feel them at all. I bought these via Amazon because I knew I could return them with no questions asked. They are not going back! I took a ride this morning that included a downhill runs where I easily spend a three or four minutes above 30 mph. I did not need to increase volume because there was no wind noise. I did hear my wheels on the blacktop. I also heard barking dogs and people saying hello as I passed. I heard the ice cubes in my water bottle clattering around. Wind noise was almost completely eliminated. When I passed 35 mph I did hear some very moderate wind noise. So little that I didn’t need to up the volume. These things really work well. The key to being happy with this product is all in the installation. Read the instructions and follow them. I adjusted my front helmet straps so that the wind-blocks were just in front of my ear. They conformed to my face perfectly and directed the air away from my ears. Build quality is excellent. These should last for years!   — Bob L

These work great for me. I have a Garneau Raid helmet and a small-medium head. With the way the helmet fits me, the Wind-Blox is a bit longer than the strap, but I was still able to attach it. My helmet is actually a little more comfortable and fits more snugly with these attached. They do not block 100% of wind noise, but they eliminate the worst noise, the high-pitched wind that seems to go directly into your ear canal. With these, the wind sounds more distant and more like a hum. I wear earbuds while riding on a bike trail, and the Wind-Blox make it much easier to hear the audio. This allows me to turn the volume down considerably, so now I can also hear external sounds better. The materials seem to be very sturdy and top-quality. The velcro is strong and the outside feels like soft neoprene. — TSB224

These things are so great! They make cycling in the cold and wind so much more comfortable. I don’t have to try to jam my helmet down over a hat, and the vents on my helmet can keep working so I don’t overheat. They fit on the sides of my helmet without any fuss and stay in place without annoying me or pressing on my ears. — S Turpin

I use a competing item from https://wind-blox.com, which I have posted about in the past. I switched helmets recently to be able to install my ginormous rear view mirror (the previous helmet didn’t have the slots I needed), and I quickly realized I needed to move my wind-blox over! Dollar-for-dollar, one of the best purchases I have made as far as increasing enjoyment of cycling. — Fitz Chivalry

When you cycle, of course, with a bicycle helmet on (!) Therefore, it is smart that you can add WindBlox to the helmet straps, in front of the ears. The barrier ensures that the wind is prevented from whistling directly into your ear canals. Thus, wind noise is significantly reduced.     — Aspie DK blog

We’ve covered Wind-Blox before, and been surprised by the results. If you’re sick of getting freaked out by people whiffling past you without warning, Wind-Blox can help.  These seemingly simple strap covers velcro in place in front of your ears to reduce wind noise at speed. This, in turn, lets you hear much, much more of what’s going on around you and behind you. The refined Wind-Blox Pro edition is a slimmer design than previous iterations, and doesn’t interrupt the clean lines of your helmet strap as much. In testing, they work a little better than the original Wind-Blox to, especially when you’re moving pretty fast down the road. — Bek SLOCyclist.com

If you cycle, especially if you cycle around traffic where hearing is crucial to your safety, I would consider spending a few bucks on Wind Blox to improve rides. — Sarah McMullin SimplyFitandClean.com

I used the Wind Blox Pro for 7 rides during my testing, each time I found myself turning my head to the side, putting my ear into the wind, then back again, to truly realize what I was experiencing. It was fantastic. I could hear…cars, that’s the most important thing. I also heard cows (remember, rural Wisconsin). — Best of Life Magazine

I could hear a car approaching me from behind at approximately a distance of 250 metres. Without the WindBlox, I certainly would not have been able to hear it until it was within 100m of me. — Tyres and Soles

They go on easily, fit with most of the helmets I tried, and are pleasantly inconspicuous to onlookers. — James Huang Cycling Tips

At age 73 my hearing has diminished somewhat. I ride on the street a fair amount so like to hear what is going on around me. I strongly believe that I am able to hear more with the wind blockers on my helmet straps. I will continue to use them. — James Ralston

5 Stars! I believe the Wind-Blox is the perfect compromise between aerodynamic drag and noise reduction. The Wind-Blox was designed as a safety item. With great wind noise reduction, I strongly recommend this product, especially for the commuters. A true 5/5 stars!    — Biketestreviews.com

I mainly bought these to get some wind reduction when listening to the radio (with earbuds) and they work great for this purpose. Up to around 20mph and in average wind speeds these are perfect!” -Amazon customer — Amazon Customer

My ears are warm and toast now These attached to my Smith helmet straps easily and don’t seem to slip. I wanted them more for warmth than to block wind noise. — Sandy

Wow! I didn’t expect that the Wind-Blox work so good! Although they don’t block all wind noise, they block enough to enjoy riding my bike again without having the roaring wind sound in my ears. And this is very important because I have tinnitus and don’t endure constant and loud noise. — Chris (Switzerland)

A remarkable distance in wind noise and discomfort. My initial solution was to wear ear plugs, but those roared almost as bad when the wind hit them. These simple attachments do indeed reduce 60 to 80 percent of the wind noise. I still hear wind, but drastically reduced. On colder days I wear ear plugs as well, but only to keep cold ear from my infection prone ears. When I first put them on my helmet strap and started riding, I could still hear light wind noise. I was annoyed, but as noted in the included instructions, while still riding, I lifted my helmet strap away from my ear. The difference is remarkable. I recommend these for everyone. — Amazon Customer

Worth It — Back from my 1st ride with the wind-blox. Excellent noise reduction. I have ear buds in and used to have to turn up the volume really loud. Today, I had the volume really low and heard everything clearly. — Conrad Ogletree

I wear a hearing aid that amplifies all wind noise when I’m riding my bike. The Wind-Blox cut out almost all of the noise. They are easy to attach to the bike helmet and are very comfortable. — TM Gadget Lady

I always use Wind-Blox with whatever headphones I am wearing, which helps with all kinds of headphones, even open-ear ones. I mainly listen to podcasts, and can hear them clearly with all of these headphones… — Average Joe Cyclist (a Canadian blogger)

I wear a hearing aid that amplifies all wind noise when I’m riding my bike. The Wind-Blox cut out almost all of the noise. They are easy to attach to the bike helmet and are very comfortable. — These are amazing!

“My wife and I use these and love them. There is no feedback and we are able to hear much better.” — David

Wind-Blox really do work. Blocking out a significant amount of wind noise so that I, as a person with hearing loss, can wear my hearing aids while riding and communicate better with my fellow riders. And more importantly, hear traffic behind me! In winter they have the added advantage of keeping my ears warm :). — Julia

I wear 2 hearing aids and am a very keen road cyclist.  This would really help with the wind roar.  — Alex

I use Wind Blox while commuting on my ebike. Without them, the wind noise from ~25mph can be really annoying. They don’t eliminate the noise, but they get rid of the ‘howling’ and make my time on the bike more enjoyable. Thanks! — Rich

Using my new Wind Blox to have better conversatins with my Daughter/stoker on her “Bike Path to College”. — Phil

I love, love, love mine!!! — David

I highly recomend these.  It is a good feeling to be able to hear clearly with out the wind noise.  Being aware that a car is approaching is such a secure feeling.  If you wear a helmet, Wind-Blox are, in my opinion essential. — Sandra

“Love ’em they work GREAT! can hear well yet the ears are protected and comfortable now. very happy with the product   — t

“Last winter I had to stop biking due to the cold, but this winter I bought these and haven’t had any issues! They keep my ears so warm! Love them!” — Amazon Customer

“It blocks wind and therefore noise is not affecting your biking and you could be aware of what’s going on around while biking…plus it’s really comfortable on the helmet and ear.” — Arnoldo

“Game changer for winter commute These are fantastic! Easy to slip on, yet hold firmly in place with Velcro. I’ll never forget these and have frozen ears. These block the wind, as advertised, while not completely blocking the traffic noise. Perfect for commuting in the winter (freezing temps for me).” — WBL

“Even at higher downhill speeds it is a huge difference…. Thank you again for a great product.  Hope to see it in stores.” — John

“I’ve put these on my helmet and they make a huge difference in reducing noise levels. Highly recommended!” — Michael
