Unlike most reusable earplugs, TradeSmart disposable earplugs are rated NRR 33 for hearing protection. This helps prevent permanent hearing loss as well as temporary or permanent development of conditions such as tinnitus (ear ringing). Besides providing top-of-the-line hearing protection, TradeSmart earplugs are made out of high-quality BASF foam, meaning they fit into your ear canal comfortably. We made them this way so you can wear them all day, enjoying maximum safety precautions - comfortably. Since they’re so comfortable, you can use these earplugs for many use cases besides at the shooting range and hearing loss prevention. Our customers like using them for better quality sleep, where they find help with distractions such as snoring, or when you want help relaxing in a louder environment. Traveling by train, bus or plane is a good example. Some like to use them at work as well, to help with focus & concentration, and some like having a few pairs ready in case they go hunting, come across a fair, concert, motorbike parade, and other cases where you want to have fun & enjoy an event or activity, but not worry about hearing loss or damage for you or your family at the same time. Note that you can also comfortably use TradeSmart earmuffs while wearing your earplugs at the same time. In fact, this would equate to wearing NRR 38 hearing protection. So the two not only fit together perfectly, they also provide additional benefits. Like with all our products, we make earplugs while keeping our motto in mind: Be safe. Be smart. Our earplugs are tested to all international standards including ANSI, AS/NZS & CE, and rated ANSI NRR33, and NRR38 if combined with TradeSmart earmuffs. TradeSmart earplugs come in 200 pairs of 2 (400 pieces of earplugs total). Available in Muzzle Flash Yellow and Hot Pink colors.
