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 ## 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.co.th/products/735082825-noizebarrier-micro-black-v4-11029](https://www.desertcart.co.th/products/735082825-noizebarrier-micro-black-v4-11029) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-07-05*
