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

These custom-molded earplugs have been a game-changer for my trap shooting sessions. After 1.5 months of regular use, I can confidently say they're superior to traditional hearing protection options, especially if you're tired of over-ear muffs getting knocked around by your shotgun stock. The molding process might look intimidating at first, but it's surprisingly straightforward and user-friendly. Once molded, they provide an almost perfect "snap-in" fit that's far more secure than disposable foam or wax alternatives. The noise reduction is impressive - they block out exactly what you need them to while maintaining a comfortable fit. Two minor criticisms: First, the lanyard needs to be purchased separately, which feels like an unnecessary upsell given how essential it is for keeping track of the plugs. Second, the initial molding process, while easy, can make some users nervous about getting it right (though it's actually quite foolproof). Compared to traditional ear protection options: - Superior fit compared to generic foam/wax plugs - No more interference with gun stock like over-ear muffs - Reusable and durable - Excellent noise reduction Pro tip: Take your time with the molding process and don't rush it. The results are worth the extra few minutes of careful attention. Bottom line: Despite the lanyard being sold separately, these are absolutely worth the investment for any serious shooter looking for reliable, comfortable hearing protection that won't interfere with their shooting form.

Update 10/25/25 I used the Decibullz earplugs at the pistol range and it performed noticeably better than cheap foam earplugs. Cheap plugs are not enough for me at the pistol range, but the Decibullz alone was suffcient. I would rank the Decibullz at just below cheap plugs with muffs. Decibullz with muffs does an outstanding job of reducing gunfire. I plan on using Decibullz and muffs at the rifle range where local shooter love to use muzzlebrakes. Original review: I was worried about molding these to my ears and whether they would really make a difference compared to traditional foam ear plugs. Turns out that these really deliver what they promise. First, the molding is easy and works perfectly if you follow instructions and watch the video. Start by attaching the plastic ear plug and plastic backing to the mold. Do one ear at a time and keep track of which ear mold is being molded. Check the thermoplastic mold for either a R or L to know the difference. Then heat water to boiling and pour the water into a coffee mug. Place the mold into the mug. Do not put the mold into water that is boiling. Wait 5 minutes. Use a timer. After 5 minutes remove the mold from the mug with a metal spoon and place it onto a plate for 30 seconds to cool. After 30 second put the plug into your ear hole and mold the thermoplastic so that your entire ear conch is covered and sealed. Wait until the mold is hard, about 2 minutes. Repeat for the other ear. If you need maximum hearing protection, remove the plastic plugs and install the rubber ear plugs. I will update this review after I go to the shooting range.

*“The best fit I’ve ever had – just a few tweaks and they’re perfect for work, sleep, and concerts.”* --- ### Why I Bought Them I’m a freelance sound engineer who spends half the day in noisy studios and the other half trying to catch a few hours of sleep in a city apartment. Over‑the‑counter foam plugs either “pop out” after a few minutes or muffle everything so much that I can’t hear alarms or my phone. The 31 dB rating promised a solid reduction without completely cutting off useful sounds, and the custom‑mold promise sounded like the perfect middle ground. --- ### The Ordering & Fit Process (5‑minute summary) | Step | What I Did | Tips | |------|------------|------| | **1. Impression Kit** | Mixed the silicone, pressed it into my ear canal with the supplied applicator, waited 5 min, then removed the set‑in‑place impression. | Keep the ear canal clean and dry before starting; a quick wipe with an alcohol pad helps the silicone cure evenly. | | **2. Shipping** | Sent the impression back in the prepaid envelope. | Label the package clearly and drop it off at the nearest post office within 24 h to avoid any delays. | | **3. Receive the Molds** | Got two identical earplugs in a small, sturdy box (plus a tiny cleaning brush). | Store them in the provided case when not in use; the silicone can pick up dust over time. | | **4. Insertion** | Gently pulled the outer ear up and back, slid the plug in until it “clicked.” | Don’t force them—if you feel resistance, rotate slightly and try again. The click means the flange is seated properly. | --- ### Performance (What the 31 dB actually feels like) | Situation | Noise Level (dB) | What I Hear | How Comfortable | |-----------|------------------|-------------|-----------------| | **Live Concert (≈95 dB)** | Reduced to ~64 dB | Music is still clear, but the crowd roar is softened. | No pressure after 2 h; they stay in place. | | **Construction Site (≈85 dB)** | Reduced to ~54 dB | Heavy machinery is audible but not painful; I can still hear safety alarms. | Slight warmth after 3 h, but no pain. | | **Bedroom (≈45 dB street noise)** | Reduced to ~14 dB | Almost complete silence; I can still hear my phone’s vibration. | Perfect for falling asleep; no “plug in the ear” feeling. | | **Studio Monitoring (≈70 dB)** | Reduced to ~39 dB | I can still pick up subtle cues in the mix, which is essential for my work. | Comfortable for long sessions (up to 6 h). | **Bottom line:** The 31 dB rating is a sweet spot—loud enough to protect you, quiet enough to stay aware of important cues. --- ### Pros 1. **Perfect Fit** – The custom molding eliminates the “wiggle” you get with foam or generic silicone plugs. No more readjusting every 10 minutes. 2. **Consistent Attenuation** – The 31 dB reduction is reliable across frequencies (125 Hz‑8 kHz), which is rare for cheap plugs that only block high frequencies. 3. **Durable Material** – Medical‑grade silicone feels soft yet holds its shape for months. I’ve used them daily for 4 months with no cracks. 4. **Easy Maintenance** – A tiny brush and the included cleaning solution keep them hygienic; a quick rinse with warm water works too. 5. **Discreet** – They’re low‑profile, so they don’t stick out in a professional setting or on stage. --- ### Cons 1. **Price Point** – At ~$45 for a pair, they’re pricier than bulk foam plugs. However, the lifespan (6‑12 months with proper care) makes the cost per use comparable. 2. **Initial Time Investment** – The impression kit takes about 10 minutes, plus shipping time (usually 3‑5 business days). Not ideal if you need earplugs immediately. 3. **One‑Size‑Fits‑All for the Ear Canal** – While the outer shape is custom, the internal channel is a standard size. Extremely narrow or unusually shaped canals may feel a tiny bit tight. --- ### Who Should Buy Them | User Type | Why It Works | |-----------|--------------| | **Musicians / Concert‑goers** | Protects hearing without sacrificing musical fidelity. | | **Industrial Workers** | Blocks hazardous noise while still letting safety alarms through. | | **Travelers & Sleepers** | Comfortable for long wear; reduces snoring and city noise. | | **Audio Professionals** | Allows precise monitoring in loud environments. | | **Kids with Sensitive Ears** | (Only if you can get a parent‑supervised impression) – the custom fit prevents the plugs from falling out. | --- ### Tips for Getting the Most Out of Them 1. **Re‑mold Annually** – Ear canals can change slightly with weight fluctuations or age. The company offers a discount on a second impression kit. 2. **Store Dry** – After cleaning, let them air‑dry completely before placing them back in the case. Moisture can lead to odor over time. 3. **Rotate Usage** – If you wear them >6 h a day, give your ears a 15‑minute break to prevent mild skin irritation. 4. **Use the Carrying Case** – It’s small enough for a pocket or a studio bag, and it protects the plugs from bending. 5. **Check the Fit Periodically** – If you notice a “loose” feeling, gently push the flange back in; the silicone will reseat itself. --- ### Bottom Line Custom‑Molded Earplugs with a 31 dB attenuation rating deliver exactly what the description promises: a comfortable, secure fit that reduces harmful noise while still letting you hear what matters. They’re a solid investment for anyone who needs reliable hearing protection on a daily basis—especially professionals who can’t afford to lose audio fidelity. **Would I buy them again?** Absolutely. The only thing that could make them a perfect 5‑star product is a faster “instant‑fit” option for those who need earplugs yesterday. Until then, they’re the best blend of comfort, protection, and durability I’ve found on Amazon. *— A sound‑engineer who’s finally slept through a night of city traffic, thanks to these plugs.*

Waste money the ear plug doesn't work and is too big

I work in a heavy industrial setting. We have sounds that are constantly 90db +. With just the silicone tips it was night and day. The moulding process was easy and they locked in very well to my ears. Unfortunately my pair did not come with the foam tips to increase the db protection level, i did contact the manufacturer and they were willing to send me some replacement tips but Canada post at the time was on strike, and they are a US company. I still wore them under my radio pelters and it really helped up my protection from all the noise that my oelters failed to block out. Unfortunately I lost my pair in my coveralls during laundry day, but will be getting another pair in the future as i did enjoy their comfort and ease of use. I will probably choose a high vis colour next time as black is easy to lose in a bag or pocket, as well co workers can see that you have them in.

I’m actually shocked how good these are! The noise reduction is amazing. Very easy to mould. Crammed the first one in really well and it worked perfectly; but gentler with the second so needed redoing but again, very easy. Bought for when I’m on the bike. No tinnitus after riding and comfortable when in. The only reason they lose marks for comfort is when taking my lid off, its very painful due to the hard plastic wedge in my ears.

Makes motorcycle touring much more pleasant, can hear whet you want to hear but that wind noise just goes.
