Home » Ear Protection

I'm picky about taking care of my ears. I'm a musician - they are kind of important to my livelihood. So I was looking for a way to create earplugs that were comfortable AND effective. I ordered the Radians kit to "roll my own." Worked great. Then it dawned on me...wouldn't this fix my problems with my cell phone's Bluetooth headset? And it did.

Here's the deal. I use a Jawbone Icon. It sits inside my ear - no outer ear clip. After an hour or so, it becomes noticeably uncomfortable. So I thought, maybe I can combine the Radians molded material with the headset, to make a comfortable, custom fit. Bingo!

I took the headset, and attached the smallest of the rubberized covers and adjusted it to fit my ear. I then mixed up half of each of the Radians materials, stuck it in my ear (just as if I was making an ear plug), then pressed the Jawbone gadget into the plug, gently molding the material around the business end of the headset, making sure to completely cover the rubberized cover. I let the material cure for 10 minutes, then removed the whole thing from my ear. After another hour of letting it cure, I used an electric drill/bit to drill about a 1/4" hole from the outside, down where the material went down into the ear canal. After a little judicious trimming with an Xacto knife, I was done. I poped the Jawbone icon back into the molded piece, and...Presto! I had a Bluetooth headset, custom-fitted to my ear.

How does it work? Perfectly. I mean, it's every bit as good a seal (if not better) as what you get on an expensive set of noise-blocking earbuds. Waaaaay cool.

So if you're dissatisfied with the fit of your Bluetooth headset, this is the stuff to buy to fix that problem, once and for all.

I was looking for an option to make molded ear plugs to wear with my half helmet on extended motorcycle rides to cut wind noise.

After a lot of research online I settled on these. I was a little concerned with the negative reviews but felt the positive ones outweighed the numbers and of course if it did not work as advertised I could return the remaining product.

Well I did not have to be concerned because it worked just like it says it will. I followed the instructions and the plugs came out perfect.

Actually, I changed one part of the instructions in that I used what they recommended for one plug (half the material in a package) to create a set of earplugs - there was more than enough material.

So for the cost of material for one set of ear plugs I was able to get two sets of ear plugs. Pretty good deal if you ask me.

Interesting note: As the material starts to cure it makes a type of crackling noise which you hear quite easily. I was a bit unsure of it initially but just allowed the curing to continue without any issues.

I definitely recommend this to anyone looking for a custom option for hearing protection.

Bottom line is that these earplugs work very well, but they are tricky to make, and I think that more material should be provided for the customer to experiment with.

First off, the material that one uses to make the earplugs (two different types of putty) has to be taken out of the container it is packaged in, and then each putty has to be divided evenly in half before it is mixed thoroughly with its opposite to activate the curing process. Kind of confusing. Why doesn't it come pre-separated in the correct proportions? This is a simple thing which would have made this a lot easier to use.

Then there is the amount of putty in the package. If you follow the instructions you will have exactly enough to make two earplugs. This allows no room for error, or to make another earplug if one doesn't come out very well. At this price, more putty should be supplied.

The earplugs I made were quite large in the end, and it would have been nice to try making a smaller set. And though they were kind of tricky to put in, they DID work very well in blocking sound. However, I bought these to be used while sleeping but they were much too big and hard for that-- quite uncomfortable. If I could have made a smaller pair, they might have worked (as is pointed out in other reviews which used half the amount recommended) but in my case, after following the directions there was no putty left.

This is a unique and potentially great product which needs better packaging and presentation.

As indicated on another review ensure you use just half of the indicated on the user guide so that you can make 4 plugs (divide each color into 4 pieces). I made the mistake on my first one to use as recommended and the result was not good, I used just half on my second one and it looked better and felt also firmer so I was able to make a 3rd one with the rest.

I bought this product after having custom hearing protection made by a professional and being thrilled with them (Insta-Mold). I have severe noise-induced hearing loss and use plugs whenever I am in an environment where excess noise exists (power tools, riding a motorcycle, etc.) I have been using foam plugs for 35 years and while the noise protection is good the comfort level is less than ideal. I often need to remove the foam plugs after a few hours to take a rest. The custom plugs are basically forgotten once inserted, going completely unnoticed except for the blissful quiet when worn.

Like others I also wanted to give this home product a shot (at a sixth or less of the cost of customs) and wanted to make custom molds for my in-ear headphones (Etymotics). Being able to block outside noise so I can turn the headphone volume as low as possible is critical with my hearing problem.

I gave the product 3 stars because while I think there is potential, the buyer is going to have difficulty reproducing the results they would get by going to a professional. There are several reasons for this. First a professional will use a small foam piece on a tether to block the mold material from reaching the eardrum. This, combined with using a large syringe to push the material into the ear gives a much better fit to the inner contours of the ear canal. Comparing the professional version side-by-side to this product it is obvious that the inner ear part of the mold is much different - the professional version being much "thicker", better matching my inner ear and providing a better seal. Since the fit is what it's all about, that makes a huge difference in how much noise will be blocked. If you are making custom headphones the seal also dictates how good the bass response etc. will be.

I have now made two pair with this product and while the second attempt is better than the first they cannot even come close to the fit, comfort, and noise attenuation of the professional product. I am still working on it though, I hope to buy some syringes and make some foam inserts in an attempt to duplicate as closely as possible the professional effort. In the end it will be worth it if I know I can make custom headphones whenever necessary.

I will keep using professionally made plugs for noise attenuation and hopefully use these for custom in-ear headphones. The extra hearing protection of the professional versions is worth every penny when the best hearing protection is the most important consideration.

I purchased a set of these, followed the instructions exactly, and they never set up, even after an hour in my ears. It was difficult to remove the gooey putty from my ear afterward, and had to have a someone with tweezers help me.

I thought that I would be different from the other reviewers that had problems, as I figured that they didn't do something right, but the pulgs still didn't work for me.

Customer service was a nightmare. I repeatedly called and was told that I had to talk to a certain guy, who seemed to always be at lunch. After I finally got a hold of him, He hastily took my address and said he would send me a new pair. He couldn't give me a reason why the new ones he were sending me would work, while the old ones didn't.

It has now been almost six weeks, and I still have not received the replacement pair.

Don't throw away your money on these.

The first package I sent was defective. I followed the instructions exactly as indicated. Took half of each and mixed careful and very thoroughly and placed in ear. Then repeated again for the other ear. After 10 minutes, the goo was not hardening. After 30 minutes, nothing. So I left that stuff in my ears for 1 hour and 20 minutes. NOTHING. I had to dig the gooey stuff out of my ears and clean them repeatedly with q-tips. Two *DAYS* later, the product finally hardened. Other reviewers reported a similar experience.

I contacted the seller, "OutdoorBunker" via Amazon and they quickly shipped another package, no questions asked. I tried this batch, performing the EXACT same procedure as before, and they started hardening in 10 min like the instructions said. I now have a custom set of earphones! Time will tell if they are comfortable and if the Radians holds up.

I don't know why the second time around worked. The packaging looks identical. The product felt the same. I suspect there is either a shelf life or a bad batch of product was out there.

I had high hopes for these, especially with how much more they cost compared to regular foam ear plugs. I followed the mixing and fitting directions to a 't', and the results were terrible. Once cured, the material is stiff enough that there is no "give". (They're also very uncomfortable, but I'd put up with that if they worked). The slightest movement makes them shift and lose the seal, letting in all sound. I bought these for the gun range, to double up under muffs when shooting rifles. These aren't even good enough to wear in bed when my wife wants to watch the late show!!! Unless I'm constantly pressing them into my ears, there's no seal and the sound goes right past them. If I do manage to get them to work somewhat, the slightest movement makes them dislodge enough to become totally ineffective. I'd imagine they must have tested these before putting them on the market, but I'd sure like to know what their process was. My money is wasted, as these went in the trash. But I'm sure telling everyone I know (and a whole lot of people on gun forums) that these don't work. You will be better off with 10 cent yellow foam ear plugs from the hardware store.

Tried both pair of Radians ordered. Followed the directions carefully. Neither would harden - even after 40 mins. Called the company and was promised replacements that would work. Never received them. Called again. Still no replacements. Do not purchase this item.

I was dissapointed in the product overall. It took almost 20-30 minutes for the product to set up to the point that I could remove it from my ear. After finally setting up the product did not seal as well as the standard foam ear plugs. Unfortunately I would not recommend this product..

this stuff would not cure.....3 hours later still the same..followed all directions....still very soft and gooey...dont waste your money!!! feel ripped off!!!

Terrible product, and if you read other reviews it is fairly obvious that they are having major quality problems. Tried to call Radians and never got an answer on the 877 number on the website. Getting my money back for these.

Followed the instructions, even watched a Youtube video produced by the manufacturer. Had them in my ear for over 45 minutes and they never firmed up. Took me an hour to clean my ear canals out. This is a dangerous product that simply doesn't work.

After religiously following the instructions, the mold never firmed up. Even after and hour, even after a day. Threw it away. Worthless.

I purchased this in hopes of getting away from using the foam ear plugs when riding my motorcycle.

The instructions were clear, and the process straight forward. The issue is they shrank when they dried and therefore were lose. Wearing them while riding I still had a very high wind noise level.

I threw them away and went back to the foam.

i purchased this specifically to make some custom molds for my earbud headphones. Do not attempt to create custom molds for Ultimate Ears Triple.Fi 10 earbuds, it will just not happen. I tried with other brands and could not create a good enough seal to lock in the bass. I was able to create them with Meelectronic's M9 earbuds, with good results because they are a smaller and lighter earbud.

It states on the packaging that it will setup with 10 minutes. This will not happen, you will be pulling loose flowing material with the consistency of silly putty out of your ear after 10 minutes. I would suggest leaving them in for at least 30 minutes to 1 hour to get the least distortion from your molds. also, if you are going to sign or talk when using the earplugs, keep your mouth open during the molding.

the results - not completely sealing....when they cure, they slightly shrink. perhaps you can brush a few layers of lacquer to account for the shrinkage. they will not slip out if i tug on the wire or move my head quickly....however, they are just a little loose after curing.

also, split the mix in 4 for each color. this will give you 2 pairs of molds. just splitting it in half will use up way too much material

So I followed the instructions to the letter. Stuck the stuff in my ear, and waited 10 minutes. Still just as runny as when mixed.

I waited another half an hour. Nothing.

At this point, I just wanted the crap out of my ears. Guess what:

Stuck. The putty got stuck in my ears. Not only stuck, but when you mix this stuff, you'll see is really a runny goo. So guess where it ran? To my ear drum. I have an appointment with an ENT for tomorrow to try to clear my clogged ear. This stuff is GARBAGE.

Let me reiterate: DO NOT PURCHASE THIS PRODUCT. I have an email in to Radians, and I plan on sending them the receipt from my ENT visit. I'll follow up with what they do, but I will NEVER use a product from them again. Let's see how they do as a company, now.

I am a drummer and currently play in a loud heavy metal band. I also play drums in church and for church functions. I bought this to fabricate my own in-ear monitors to use for live shows and practice. I fabricated the plugs just as the package described(using a water bottle cap between my front teeth to keep my mouth open so the plugs would form correctly) and then put $5 big-lots isolation headphones into my ear canals(not too far, you can't do this wrong or you will hurt yourself permanently) where they would normally fit (while the radians plugs were still wet and pliable). I let them dry for 10 minutes, pulled them out, cut holes where the speakers in the headphones are(it didn't stick to my ears or my headphones), and plugged them into my personal mixer. I practice daily, 1 to 5 hours with these monitors in. They never fall out, the drums sound amazing, and the outside noise is nearly eliminated. I recommend this to all my musician friends as a cheap alternative to going to an ear doctor, getting pro molds made and spending hundreds on a set of headphones that may last as long as the big-lots headphones. This was a great and affordable way to make my own in-ear monitors.

I have been using the same plugs now for over a month, I can clean them with rubbing alcohol, my ears don't ache, they are comfortable and like an unnoticeable, awesome addition to my practice routine. I would and have been recommending this to all musicians. I am currently disciplining myself to beat the world records for fastest hands and fastest feet. I'm at 1000 beats per minute with both hands and feet. This is definitely an excellent product to help in my endeavors!!!!

I would also like to add that it was my first time doing this, I did one ear at a time and didn't mix the portions until I was ready to put them in each ear. It really does set up in 10 minutes. If I have to do it again, I will use smaller portions for each ear because I was able to make a back up set of plugs with the left overs, but they are a little smaller and probably not as reliable because there's not much material on them. These seem like they will last forever if I take care of them the way that I do now. I can also pull the headphones out of the radians, and replace them if the headphones go bad. Really awesome product!!!

After reading some of the other reviews, I would like to add that I am extremely disciplined, I read and follow instructions carefully, and I tend to be a perfectionist or at least very thorough in the things that I do. If you are kind of clumsy, or don't trust your abilities to do this stuff, I wouldn't try to do it without help because you can damage your ears if you do this wrong or push the material too far into your ear canal.-It does say in the directions not to push it into your ear canal. DON'T PUT IT IN YOUR EAR CANAL!!!!!

GREAT STUFF!!!!!!!!

These mold in to your ear quite easily (be sure to go deep), but never seem to go back in to the ear properly after they're made. I can't get a good seal on one ear at all. Ordering a second pack of these and trying again gave me the same problem. They just don't seem to have enough flexibility and smoothness to allow them to get back in to my ears.

I have been a light sleeper a.k.a. insomniac for years, not to mention my wife talks in her sleep and the dog snores. I have used this product for the last year as earplugs when I sleep. I make a smaller sized plug so that there is no discomfort when lying on my side. I can still hear if the dog starts to bark but it helps to block all the nuisance noises such as a leaky faucet that drive a person crazy when they can't sleep.

Steps:
1) I take about a third of the putty from each vial and mix the two together until the color is even. (you might need more if your ears are larger...)
2) Divide the mixture into two even pieces and roll each into miniature carrot shape.
3) Insert the small end into your ear canal and press the remainder to flatten even with the opening of the ear.
4) Wait 15 minutes then remove and allow to it sit and cure for a couple of hours.

I just purchased this last pack to make a set for my step daughter who has been having a hard time sleeping. After she had gone down her own route of taking melatonin and other herbal things to try and sleep, she relented and decided to try my remedy and slept like a baby the first night, no adjustment period at all.

This product is awful in this form. It never set and also it is difficult if not impossible to get a good form without injecting the stuff into your ear. I actually spoke with the manufacturer of this and he said there are so many problems with it he refused to let his company name (the supplier) to be associated with it. The product when it is fresh and used correctly is brilliant. I had some molded earphones made from this product at a motorcycle trade show and it was perfect. This do-it-yourself kit however is not the way to do it. Yes, you might be able to get somewhat of a mold however it will be inferior to the mold kits that allow you to inject the stuff deeper into your ear canal.

product never set up and remained goo. difficult to get it out after.

I cant stress enough how bad this product is

I should have listened to the reviews.

I did as many others thinking I could do better. Nope.
I cleaned my ears, then my hands. I smashed it all together and made one big ball of a mess until it was all mixed. Took small chunks of the big pile and put it into my ear. I sat waiting. 10min, 20min, 40min. Nothing. I pulled what was a red silly putty from my ear. It is still tacky, and will not even stand on its own. So bad that I had to clean my ears and hands again.

I placed the pile out on the table at 10pm. The next morning, it was still tacky enough I could reball it up and stick it to a wall if I felt the urge to throw this stuff around.

*IF* you even buy this stuff, do NOT let the color portion rest anywhere. It can stain if left unattended.

After reading the other reviews, I did not even bother trying to get my money back.

Due to so many negative reviews, I wanted to share my experience and impression of Radians Custom Molded Earplugs. If you are expecting to get a perfect result the first time, you may well be disappointed. If you like to play with stuff and experiment a little, you might really like this stuff. I think that even if you go through several packages to get the results you want it's still a pretty good deal.

My first attempt with making custom earplugs with Radians Custom Molded Earplugs did not turn out so well. I followed the directions sheet (clean hands, clean ears, dividing in half, mixing 45 seconds, etc.) but the material did not set up. It was still gooey 24 hours later when I returned it to the store. After reading numerous accounts from other users I guessed it likely the two parts were not mixed as completely as I'd thought and decided to give it another try. I could not read the date inside the first package.

I bought a second package at the same store as the first, changing color choice just in case the first had been a bad batch or old or something. The date in the second package was from eight months earlier - I am assuming this is a manufacture date, not expiration. This time, I mixed all of both parts together at once to eliminate the possibility of not getting equal parts of both halves and mixed them pretty aggressively for about 3 1/2 minutes. The consistency had started to change at about 2 1/2 minutes and in hindsight this is probably about the point I should have stuck it in my ears (I think it's more of a feel to the mixed product than a set time as different people will mix differently - it seemed to become less shiny at about 2 1/2 minutes for me and I think that's an indication it's mixed and ready). It set up within 10 minutes and was easy to remove and put back in my ears. I gently bit down on a small medicine bottle as recommended in another review while they were setting up and this seemed to help give a little better seal. It was already firming up a bit when I put in in my ears so it did not form into the ear canal as well as I wanted. My next ones should come out better now that I know what to look for while mixing.

What I learned from working with this stuff is that there's some learning curve to getting a good result. It's not complicated, but it's also not as simple as they try to make it sound. My recommendation would be to buy at least two packages and make the earplugs one ear at a time from start to completed ear plug. Maybe try each new plug for a while to determine what's right, what could be better for the next one you make. Most people probably can probably get three to four ear plugs out of each package, so that's six to eight opportunities to get it right or at least learn and do better the next time. I think people are expecting to get it perfect the first time and that's simply not realistic if they have no experience working with this sort of material. I also think that after making a few and playing with it some, most people can expect to get pretty good at making something that will work well for their needs.

I think the instructions in the package and the video on Radians website give the impression that it's a super simple process. That's probably responsible for a lot of people's dissatisfaction. Some information on how to tell when it's mixed fully would be nice. Also, doubling the amount of material in the package would not lead to doubling the cost, but would allow for customers to make several practice plugs. Radians could do a lot better with the website and the packaging. They are hurting themselves and turning off a lot of potential customers even though they have something that could be a great product.

I'm now hooked on the idea of making my own ear plugs and will buy a couple more packages of Radians material to experiment with, but I am going to be looking at other good grade silicone puttys to make more after that. A quick look on Amazon show them available for as little as $20 for half a pound. That should make a ridiculous number of earplugs.

I notice there are quite a few reviews regarding this item that mention the finished product taking too long to set, or being too "wet" after setting up.

These are classic symptoms of an incorrectly mixed formula. If there is too little catalyst then it will take "forever" to set up. If there is too much catalyst, then the extra will seem "wet" once the process is complete. If the proportions are OK but are inadequately mixed, you will also get these "less than perfect" results.

The best way to avoid all of these situations is to mix EVERYTHING at the same time. Make sure to THOROUGHLY mix the compounds together. This might take 3 or 4 minutes. Mix it all together until it becomes one consistant texture and stays warm to the touch. Then cut it into 2 equal halves and go to town.

I bought two of these from two different vendors (one tan, one red). In both cases did not harden as fast as promised (in about 10 min)! It spent 2 hrs in my ears before I could take it out. It wasn't a huge deal, except you have to make sure you don't have to sleep or leave until after 2 hrs. Make sure you mix them vigorously for the full 45 min. I suggest mixing the entire material well, and then divide them into two parts, so you can make sure one half doesn't get more or less hardener than the other.

I used these to create a seal around my earbud headphones. I simply put the earbuds in my ears and smushed the mixed puddy in around them. Now I have earbuds that keep the sound out even better than advertised PLUS they don't pull out of my ears so easily due to the custom fit. Love 'em!

If you're, like me, one of those people with defective earlobes that reject earphones, try this. Custom fitted in-ear headphones cost hundreds of dollars. With this you can make your own. Worked perfectly =)

I'm a big fan of this product. These plugs are inexpensive for customs and very comfortable and effective as advertised when made properly. They have one very significant shortcoming. They are not foolproof. If you do not read and follow the instructions thoroughly or better yet watch the instructional video on the Radians website, you could be asking for some serious trouble. These are your ears we are talking about here folks do your research or you could do some damage.

Before you make or take advice to reduce the quantity of this product used for each ear please consider this. Everybody has very different ears. The bowls in my ears for example are very large. When using exactly the amount provided I was able to make molds that are very much like the ones shown. If your ears are smaller you can pinch small amounts off while it's in your ear as suggested.

Some of you are recommending people force the substance further into their ear canal. There is a reason there are specialists that are trained to make ear molds. You do NOT want this stuff coming in contact with your ear drum. The good news is that you would have to work at it to get it that far in. It shouldn't happen by accident so do yourself a favor and don't make going deep your goal.

I don't mean to discredit anyone who had complaints about this product not curing in a timely fashion after they followed the directions verbatim. Perhaps there were environmental factors, or some inconsistency in the product. That said, I think if you read the majority of the reviews you'll see that it cures just fine. If you don't mix the parts evenly and thoroughly, or worse yet put the colored part in one ear and the white part in the other all I can offer you is my sympathies and a bit of advice. See specialist and then have your plugs made professionally.

Here is what I call the popcorn rule for letting the plugs cure properly. As others have stated, at some point during the curing process it will start making popping noises. When the popping slows down significantly the plug should be fine to take out. Ultimately if it feels firm and no longer malleable on the outside you can probably take it out. You'll want pull along the outside edges of your ear to release pressure, and then gently twist and pull out the plug.

One final piece of advice is to find something around an inch tall you can gently bite down on while creating the mold allowing it to cure. I found that the ear I did this with got a much better seal.

They would not harden my ear, I pulled the mess out and let it sit. After a few hours they were still mush, only the next morning did they harden up in a big lump. Not a good product. I returned to amazon.

I just noticed that this item is "Under Review" by Amazon when I went to order another kit because my dog chewed up my set. It's possible that people are expecting too much from a ~$12 custom molded ear bud. Comparable custom fittings from an audiologist are upwards of $150.

This kit works exactly as advertised if you take your time. There is enough material to make 2 full sets of plugs, so you can use the first as practice and if you don't get it perfect, make another set.

I use them to create custom molds for ear buds, and it works exceptionally well.

Most important: let it cure for about 30 minutes, longer is better!!

Next, and most second most importantly, the product works. I currently use it with a set of universal fit in ear headphones for a better seal, and it works very well (Specifically, with a good mold I have found the seal to be comparable to foam plugs, like complys or shure olives, except you won't need to replace them like you do with foam.)

As the instructions say, you need to take half of each of the containers and knead them together until it is all a uniform color (no streaks, etc) then insert into your ear and make sure the seal is good. The instructions then say to wait 10 minutes and then carefully remove. However, as mentioned earlier, I would strongly recommend waiting at least 30 minutes before removing, otherwise it has not cured enough and will still be very soft and malleable. If you're in no rush, I would wait a little longer as they tend to come out better. I think I waited about an hour the second time I did it, but I didn't keep exact time.

Another recommendation is to use about 1/3 from each container, not 1/2, if you're doing the DIY custom fit headphones, as the headphones themselves will occupy space in your ear. However, your mileage may vary depending on the size of your ears and the size of the headphones. Continuing, I would wait at least an hour after removing the earplugs before you start removing the material that is blocking the sound hole of the headphone so that you know the mold has completely cured. Also, my headphones (plastic) were completely fine after removing the mold from them, so don't worry about damaging your headphones if you don't like the mold/earplugs. (You will of course render the earplug unusable though.)

They are also very comfortable. I have worn them all day and while asleep at night without any discomfort; it is easy to forget they are there, if you're not in a noisy environment.

My only real complaint is that you really only have one chance to do it right, since you'll probably need almost all of the material to do both ears. That, and they really should advise 30 minutes to cure and not 10, as mentioned twice earlier.

Hopefully this review has been helpful, if you have any questions just comment and I'll do my best to answer them.

I got these to make some auto racing earplugs with hearing aid capsules. I molded them as the video showed after having my SO trim all the hairs from my ears (they dont mention this step in the video but I recommend it). The molds went well.

After they set I trimmed them and using an X-acto knife and drill created a place for the transducers I wanted to use (same hearing aid capsules as the $500 custom pieces use).

Everything went together well and generally they work great.

Problems...

These thing are PINK!!! not red. Here is a clue. When you mix equal parts red and white you get PINK! If I were a 100 pound female, that would be great but I am a 220 pound 6'3" guy. I heard no end to comments about my "cute" earplugs.

The silicone rubber or whatever these are doesnt bond well to anything. I have had no luck creating strain reliefs for the ear capsule wires that also bond tight to the plugs.

Purchased these to use while motorcycle riding instead wasting money on the foam ear plugs. The process of making the plugs was real easy and I had high hopes because they really reduced noise at that time. But when I went to use them I was really disappointed. They didn't expand from body heat like the instructions stated and perform about 50% compared to foam. Tried them for a week and no difference.

I bought this to make some home made in ear monitors (a little DYI thing I read). The monitors did not work out that well but custom molds work nicely. If I needed ear protection I would buy more of this. Sets up nice and is pretty easy to use. Make sure you read the direction carefully.

This stuff never hardened...

I waited for 45 mins with this stuff in my ear, constantly re adjusting it because it would get saggy every minute or two, before i fiunally gave up and threw it in to the trashcan.

Maybe itll cure properly in there, but the directions said it would set in 10 mins, and fully cure in 3 hours. Im lucky the material that was stuck in my ear still wasnt very difficult for me to remove. its very sticky

I just sat it on the table in the shape of a cone, in the time it has taken to write this review, it is has turned in to a flat puddle... this is 1hour after first mixing it.

Not satisfied w/ this product. Once they set up, they don't stay sealed in your ear if you move your jaw. Foam ear plugs conform to your ear when you move, these don't. They are difficult to put in, too. Seems like a good idea, but I don't think they work.

These were awesome while they lasted, but recently they started to crack. For the price I would have expected a bit longer life out of them than 3 months.

I followed the instructions, but the material never cured. I left the material sitting on the counter for 3 days and it was still a runny goo.

I find that this product was only mediocre for use as earplugs. The reason for this is as the product solidifies, it shrinks slightly. Not much, but just enough that if you had a perfect fit before the solidification, it is no longer a perfect fit. This makes it not so ideal with use for loud noises. I tried it out when I went shooting and it performed moderately. However, I then used the soft, disposable earplugs, and those outperformed this product. However, the custom molding use had endless possibilities. I followed a previous reviewers advice and used the excess to make earbuds for my mp3 player and they worked great. So, moderate use as earplugs, but the custom molding possibilities make this product worth trying even if the original use is not ideal.

Fits and molds to ear perfectly, but end product is just hardended foam (as expected). While it fits the ear perfect, since it's not a "smush" type, it doesn't expand and create that good seal like normal smush earplugs do.

I can't recommend this product. Unfortunately the mold never set for me; it just remained a gooey mess I had to clean out of my ear. I watched the video on their site, followed the instructions, and read advice from other reviewers, so I'm not sure what I did wrong. I even left it in my ear for over an hour to be sure but it remained gummy and sticky the whole time never firming up. It was a pain to clean out of my ear and off my fingers even then.

I bought two packages, just in case I mess up the first one.

Well, I followed the instructions to the letter, put them into my ears, waited 10 minutes, tried to remove the molds just to notice they didn't cure at all.

So I waited more... over an hour I waited... and nothing!

The molds didn't cure!

The horror when I saw that there was no way to remove them!

Part of the mold was left in my ear canal!

Went to a doctor, paid 100 USD for the visit.

Fast forward a couple of months.

I found the second package and thought, hey, maybe the first one was bad, this one might work.

Bad idea!

As I am writing this, I have a part of the mold in my ear. It never cured!

It's right in front of me on my desk and there is no way it's going to cure, ever.

Wrote to the Radians, never got any response.

I'm off to a doctor, again.

DO NOT BUY THESE!

After much research I went against my better judgement and ordered this. I had read many, many reviews saying that the stuff never sets up. But I had also read some good reviews so I took a chance. Lesson learned. The instructions state that when properly mixed the putty will begin setting up within 10 minutes..... Well, after over an hour I had it dripping down the side of my head. It took quite awhile to get it all out of my ear. Fortunately it had not oozed into my eardrum. It now has been about 30 hours and the lump of this stuff I took out is still has runny as the minute I put it in.

I wanted to return this crap but my 30 day window had expired. Fortunately I had purchased it from eCop! Police Supply and when I emailed them they instantly credited my account. Kudos to a top notch vendor!!! They said they had not had this in inventory very long but there was a date code on the box of July 13, 2011. I don't know if that's a sell by date or expiration date or what. I ordered this on December 27th, 2011.

My advice to ANYONE wanting to try this stuff is to mix a small ball of this and set it on a plate and time and watch it. If it does not start curing within the allotted time, DO NOT put it in your ears!! You may not be as fortunate as I was in getting it back out!

Again, I absolutely recommend eCop! Police Supply as a stand-up vendor!

The idea of these seem like a good one but then when you get it reality sets in. As with all things too good to be true feeling duped is the end result. I'm only out $15 but I still took the chance and regretted it. They are not comfortable and never seat in your ears properly after they have been molded. They also look ridiculous compared to regular reusables and you'll always be messing with them because they don't fit right. Save your money and buy a set of $3 reusable plugs that work MUCH better. If you need ear protection every day you will be much happier not buying this product. Don't be like me and disregard the unfavorable reviews of this product of which there are many.

I was a bit hesitant to buy these after reading the reviews but for $14, I thought "why not?" Last year at NRA I almost paid $75 for some glittery blue ones. Well, I took my time and carefully followed the directions and they turned out well. I like them and they stop a lot of sound, even big gun blasts.

I read the other reviews and was worried about curing to full hardness. I do not really want something hard in my ear to block sound. Everything was really easy. I cleaned my hands and ears, made one ball of each color and cut the ball in half with a knife. I rolled each half into a ball and compared them to make sure they were the same size then took one of each color and mixed them together. They blended really quickly but I continued to knead them to ensure they were really mixed well. I pushed the ball into my ear and waited about 15 minutes (both sides) just to make sure they were cured. When I pulled them out they were a little soft (a good thing) but did not lose their shape. While they were curing they blocked noise very well. I expect them to be just fine.

So, got my Radians orange earplug kit in today and I was eager to test out the process. The first thing I did was pinch off a tiny bit from both sections, mixed and set the piece between my finger to make a mold (could have used anywhere I suppose, just wanted to see it keep shape). 10 minutes later and a perfect mold had taken place! I actually did this first because I had read other reviews about the compound not setting in peoples' ears and well, I didn't want any mush in my ears. So, if it didn't work in the test then it wasn't going in my ears. Like I said, it set just fine so I was off to clean my ears and get ready to put some weird stuff in my ear for 10 minutes. Both ears completed, molds sitting out to cure and they look great. 3-4 hours later (they say to wait 3 hours for them to totally get set) I pick them up, pop them in my ears and they fit great, like they were made for me (yes, I know, they were). Getting them in takes a little practice but once you get it it's pretty simple.

Overall, love them, can't wait to take them to the gun range!

The only thing I wish was different was the color, they're supposed to be orange but once you mix the orange and the white compounds it turns into a creamsicle color (yes, still an orange but I was hoping for a brighter shade)...but hey, I can't see them while I'm using them so oh well!

I was very disappointed with Radians. I've used several of their other products the last 8 years and have been pleased. These plugs, however, were useless. In addition to the included directions, I watched the videos posted by the company on how to use these plugs. I had the plugs in my ears for 20+ minutes (10 minutes is recommended in the directions) and they never cured. Completely useless.

The plugs were easy to fit and were a perfect solution to my problem of very small ear canals. They are the most comfortable ear plugs I have ever used.
