Decibullz - Custom Molded Earplugs, 31dB Highest NRR, Comfortable Hearing Protection for Shooting, Travel, Work and Concerts

For a while, I was researching a lot of the top choices for hearing protection because my girlfriend and I were going to the Indy 500 for the first time, and we wanted to protect our ears. Having been to NASCAR races before, I knew what I was looking for and I also knew I didn't want over-the-ear ear muffs because they can put some strain on your head and cause sweat to pool around your ears. So, I wanted earplugs to counter these issues. I investigated a lot of options, but Decibullz was the first choice I saw and it stuck with me the whole time.I'll put it simply: These ear plugs are the best out there. With the slightest caveat.Most of the negative reviews for this product are due to user error. If you follow the directions and mold them properly, you will experience NONE of the issues they faced. These ear plugs were comfortable for an entire 3 hour race, no irritation, and no hearing loss at all. No sound bled through, and they didn't ever feel like they were going to fall out.The setup is pretty straightforward, but let me share what I did to make them fit absoultely PERFECTLY:1. Setup the earplugs while boiling your water. I got the case/laynard/plugs bundle, so I used the non-laynard filters and the smallest tri-flange tip they had. This is to ensure the earplug goes in far enough into your ears to get a good inner mold(very important).2. Once water and plugs are ready, do ONE PLUG at a time!!! This is crucial. The steps say to do both, but it is much easier when you can focus on one plug at a time. Let it sit in the water for 5-6 minutes.3. Gently scoop the plug out with a spoon. I used a metal spoon and had no issues. And let it cool until you can touch it. Be careful not to squeeze too hard!4. This is the most important part: Carefully put the plug in your ear. Make sure to rest it in your ear, and then ONLY push where the filter is initially. Making sure the plug is IN your ear properly is the most crucial step! And make sure it is in as comfortably far as possible.5. Begin to massage the plug into the space of you ear. I focused on pushing to the back of my ear, then massaging above my ear lobe, and then the front of the ear. And then keep pushing on the filter to maintain that seal. Keep doing this for a few minutes. Also, very useful to have another person helping, but a mirror works too to ensure the whole ear canal is covered.6. During this process, I also was squeezing my ear (top and bottom, front and back) around the mold to make sure it took total shape of my ear and to ensure it's not going to hurt my ears for being in a long time.7. Once the plugs are hardened, carefully take them out and let them cool. Then repeat the steps for the other ear plug.8. After all the plugs are molded, it is important to test the plugs TWO different times. First, test both plugs in at the same time to ensure the sound around you is at least muffled. Have some air blow into each ear. If you hear a lot of air/wind, then it is best to try and refit them to make sure your whole ear hole is covered.9. If that test passes, then you will want to switch to the foam ear tips (these offer the best noise cancellation). Squeeze the foam tips so they compress and go further in the ear. Do the same test as the last step. If you have the same issue, make sure to change the tips BACK to the ones you used initally and then repeat the steps to refit them/warm them back up.10. The plugs should significantly reduce the sound. Almost like you're underwater. But you should still be able to hear mostly everything. It reduces the noise, not cancel it out.For anyone looking to use these plugs for the same application as me (in-person auto racing spectating), then these are absolutely PERFECT!I was able to hear the cars go by at a reasonable volume, AND I could still talk to my partner between passes and hear the announcer clearly over the speakers.Because of how great these plugs were, I definitely anticipate using these for other applications (concerts, more races, anything that is loud).If you were on the fence about getting these plugs, please let this review be the sign to get them. Ignore the bad reviews, because they more than likely did not install them correctly.TLDR: Bought these plugs for IndyCar/NASCAR races, and worked perfectly for that application. I shared the steps I took to make them fit right, and experiencd none of the negatives the bad reviews shared because I followed the steps. Highly recommend getting these plugs!

These work really well with isolating noise, I use them on my motorcycle and I can still hear the radio and cars around me. It takes away the wind noise and helps with the drone from the exhaust. The molding process was easy as long as you follow the directions. These sit on my ears perfectly and do not fall out. I did start with the small ear inserts when I was molding them and then switched to medium insert once done to make sure they sealed correctly. The orang ones are nice and easy to find if you drop them on the ground.

I purchased these moldable ear plugs to wear inside my motorcycle helmet to reduce wind noise. The plugs themselves are very well designed and work great, however they do not work well inside my helmet so for that application I'll be returning to foam ear plugs.

The media could not be loaded. Some background: I'm a really light sleeper and I'm SUPER sensitive to snoring. So for the past few years, my go-to earplug for sleeping is the #M TaperFit 2, in a large size because my ear canals are pretty big. But after the last few 200 count boxes of those, I've been running into quality control issues, so I decided to try something more sustainable.Enter these moldables from Decibullz. I really did my homework here. I watched a ton of in-depth reviews on YouTube, both from folks trying these for the range and for sleeping. And almost unanimously people rave about these plugs. So I grabbed a pair on same-day delivery and decided to give them a shot before re-ording TaperFits again.Amazon delivered them, and I spent some time reading the included instructions, and then just to be safe, I re-watched videos from reviewers as well as Decibullz to make sure I got the molding process right. Since I have such large canals, I went straight to the largest silicone in-ear plug size. After hot-soaking the plugs for five minutes and cooling for 30 seconds, I inserted the plugs as deeply into my ear canal as I could and began press-molding the plugs to completely cover the inside of my conch. I had my wife watch to make sure everything that could be covered inside my conch was covered. While waiting for the plugs to cool and set in my ears for five minutes each, we were watching TV, and I had zero issues hearing the show. So not a good sign so far, but I hadn't yet put the included end-caps in yet. After the setting process, I removed them and let them air-cool the rest of the way down.Last night at bedtime I inserted the end-caps and then pressed these back into my ear. After setting the silicone plugs into my canals, I could feel them slip ever so slightly back out, but seeing as the seal around my conch was still firm, I thought it might be normal. But as my wife was asking me how they worked, I realized I could hear her almost as easily as without the plugs. I noticed I was hearing my cat bathing herself all the way down the hall, which is quiet without anything in my ears. I pushed and held them in and they were about half as effective as my TaperFits, and when I let go they were practically non-existent in my ears sound-proofing wise.So all in all, in MY ears, these are a complete fail.Comparing with foam TaperFits, here's the rub: They are both rated at "maximum NRR" of about 31dB; the TaperFits say 32, but, they're comparable on paper. But when the TaperFits fit properly, the noise blocking is great. The finger-rub test -- where you gently rub two fingers together next to your ear -- is almost silent with the TaperFits. With the Decibullz, there was practically no difference: I could hear every detail of my thumb and forefinger rubbing together.A few observations about the Decibullz that I think contribute to the failures here:* The flanges on the silicone plugs are SUPER thin and light. This means they lack rigidity to remain expanded in the ear canal, or to hold them in place from slipping out of the optimal depth and position. I can also see these cracking and breaking down in no time, as I've experienced the same on other earplugs that had flanges this thin. See my included macro-lens super closeup video clip of how they flex and nearly fold with a very SLIGHT prodding with a tiny beauty tool.* The black endcaps that go into the hard plastic hollow core are also very thin. They seem to just act like a drum, propagating all vibrations from the outside that hit them, transferring that sound straight through the tube core, and into the silicon plugs themselves.* And then there's that hard, hollow, plastic core in the center of the molding, between the endcap and the ear canal tips. Why are these hollow?!? That's just a recipe to propagate as much sound as possible! These cores should be filled with some kind of sound/vibration dampening material, instead of providing an air pocket for compression in tandem with that drum-head of an end-cap. The engineering on this is frankly laughable.So what I would say in Decibullz defense here is that earplug performance is always going to be highly subjective to a degree. Everyone's ears are different and no one single product can be pest for them all as a result. But past that, there's just some engineering decisions here that leave me scratching my head as to how so many people can say these work well enough to ditch disposable foam plugs. I can't imagine the pain and volume I'd experience with a rifle going off on the other side of these tiny drums.
