I'm just an average Joe who likes to shoot clays in my backyard. I've tried several different electronic earmuffs and while they work great at protecting my hearing and amplifying ambient sounds, they interfere with getting a good cheek weld on my shotgun. So I decided to try electronic in-ear hearing protectors. The OTTOs looked nice and got good reviews, but the price was a little more than I could justify, so I went with another brand that was heavily marketed on social media. I received them, tried them out, and wasn't very impressed with the sound quality. The wind noise was terrible and, when one of them completely stopped working after only the second use, I returned them. After watching countless YouTube videos and reading every review I could find (all of which said the OTTO ear plugs are worth the price), I bought some. These things are nothing short of AMAZING! The difference between the OTTOs and the cheaper (but still not cheap) brand is night and day. Sound quality is amazing. On the low setting, I feel like I'm not even wearing earplugs. I can communicate normally with those around me, and the sound is totally natural. IMO, there is not even a need for the high setting. It's like having bionic hearing, yet it still works fine in the wind. I shot a couple of hundred clays and when I put them back in the charging case, the digital readout showed they were still at 90% charge. So I'm not at all worried that they won't make it through a day of shooting. I do wish they came with better foam earplugs. The included ones work fine and offer good protection, but the Comply foam plugs are a great upgrade in fit and comfort. It would be nice if those were standard. Not a big deal, though. Just buy the Comply ones when the originals are ready for replacement. All said, I couldn't be happier with my purchase. These things are absolutely a worthwhile investment. Review: I am happy with this product, however I thought they would block more sound when in noise canceling mode ## Features - Up to 40 dB of impulse noise protection - Up to 15 dB adaptive noise attenuation - Hearing enhancement mode amplifies soft sounds up to 5X - Natural hearing for safe sounds - Accu-Technology high-definition sound quality - One-button touch pad, 2-mode operation - NRR: 28 dB(Foam Tips); 23 dB (3-Flange Tips) - Frequency Response: 40Hz - 16kHz - Transducers: Balanced armature receivers (speakers) - Wide bandwidth ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07SSDDND1 | | ASIN | B07SSDDND1 | | Batteries | 2 Lithium Ion batteries required.

Check their website. Otto Engineering of Carpentersville Illinois. **Q: Can volume be adjusted for each ear** A: Yes, but there are only TWO settings... and it’s not as good on sound canceling / reduction when firing weapons as a standard peltor or similar ear pro device. **Q: Is it possible to replace the rechargable batteries as they age, or you have to buy another set? (and if not replaceable, approx. how many charges?)** A: Not replaceable. You would have to buy another set **Q: Anyone use these for loud music, or concerts?** A: I’ve use these for figure eight derbies and they were great but they’re not a license Dealer and they will not honor the one-year warranty ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by T***M on 15 November 2025* First, let me say I am NOT a professional shooter.

I now run my own shooting school where I shoot indoors and outdoors. I researched like crazy to find the best in-ear hearing protection and landed on the OTTO Engineering NoizeBarriers. Outdoors is where these shine folks, they will handle everything in that environment you can throw at them. The thing I love the most is I forget they are even in my ears; they are that comfortable! I can wear whatever hat or headgear I want, and nothing gets in the way. Indoor shooting ranges are a mixed bag though. To tell you the truth, I have two pair of high-end hearing pro that professionals wear and they struggle indoors as well at times. I didn't expect these to be able to handle indoor shooting at all, but they did just fine if it was just me and a buddy shooting or if I only had 4 or so students and I could stand about 10' behind them. But, when I had more students I had to push back about 20' or more to even be tolerable noise reduction levels. So I set these to the low amplification, threw on my over the ear muffs on top of these and BAM! Perfecto combination. With them doubled up I had very good amplification and perfect noise reduction. People comment about these not being updated over the years and they don't have some of the "bling" that other in-ear devices have...such as bluetooth connection or multiple levels of amplification. These have 2 levels...low and high. The low should be called "normal" because it amplifies to a normal hearing level and makes it seem like you aren't wearing hearing protection at all. This is where I run this pretty much all the time. High is like the high end of a good pair of hearing protection. A bit too high for me for "normal" shooting on the range; I don't need to hear every pebble move as I walk. I could see the High setting great for hunters sitting in a blind or even home protection when you are barricaded and waiting for law enforcement to arrive....you will hear everything in your home! If you shoot a lot, especially outdoors, these are an amazing investment in a quality in-ear hearing pro. The build quality, reliability, and track record of these stand out ahead of all the rest on the market for a reason....they didn't change what works for a trade-off for bling you don't need when shooting. ## Frequently Bought Together - OTTO Engineering NoizeBarrier Micro, Black, V4-11029 - Comply P-Series | Memory Foam Replacement Ear Tips Designed for Etymotic, NuForce, ISOtunes PRO, Q-Jays, & More | Superior Noise Isolation, Ultimate Comfort, Secure Fit | Black (S/M/L) (3 Pairs) - 3M PELTOR Skull Screw Communication Tip Replacements, Pack of 10, CE Approved, Replacement Skull Screws Eartips, Push to Fit Style, Hearing Protection, Gray --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/470624090-otto-engineering-noizebarrier-micro-earplug-black-v4-11029](https://www.desertcart.pt/products/470624090-otto-engineering-noizebarrier-micro-earplug-black-v4-11029) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-23*
