Features:

• By using innovative attenuation filter technology our earplugs reduce noise evenly to maintain the full spectrum of sound while protecting your hearing. Music or voices won’t be muffled like with foam plugs.
• Our earplugs provide about a 21 dB drop in decibels so you can continue doing the activities you love while minimizing the risk of hearing loss. (NRR is 16 dBs)
• With two pairs of different sized earplug shells included with every order. Insert the included pair of attenuation filters into preferred shell size and earplugs are ready for immediate use!
• Our earplug’s triple flange comfortably fits almost any normal to large ear size, effectively blocking out harmful noise. Clear silicone provides low profile for subtle use. Removal is easy with a tug on the integrated pull tab.
• Included complimentary with every pair of earplugs is an aluminum-grade carrying case so that you can keep your ear plugs in easy reach. The case’s waterproof rubber seal ensures your earplugs are protected from moisture, dust and debris.
