The Rooth Protective Earpiece for Firearm users includes an advanced patent-pending "pulse filter" in order to protect the user from the damaging sounds of firearms. The pulse filter is able to attenuate even the maximum peak of a firearm's sound to a safe level, preventing the risk of both long-term and short-term hearing damage. The technology in these earpieces provides the maximum hearing protection from firearms, but maintains the clarity of normal level sounds such as speech and environmental noise. The earpieces allow for a natural flow of air into the ear canal and inner ear, reducing inflammation, while maintaining a good sense of space and directionality of external sounds. Advantages of the Protective Earpiece: The Rooth Protective Earpiece allows for accurate noise reduction while maintaining the desired signals with special filters that can be exchanged and placed into the earpiece for different noise levels and situations. While the earpiece will accurately attenuate the environment's volume level, it allows sounds that an individual will need to be aware of to be heard - sounds such as sirens or the sound of crying. The ergonomic design of the Rooth Earpiece also ensures a comfortable wearing experience. The silicone material of the earpieces are highly malleable, bringing forth unmatched comfort. With its special "Tri-Layer" design, the earpiece molds to the shape of the user's ear canal, maintaining comfort during prolonged use. Finally, every Rooth Earpiece goes through a rigorous European CE quality control process and certification to ensure a high standard of quality with highly reliable performance. The earpieces are resistant to tear, flexible, washable, and reusable. Product Material: Liquid Silicone. Noise Reduction: 25 dB. Product Diameter: 9-13 mm. Lifespan: 12 Months. Maintenance: Washable.
