The TEP-100 is a compact, lightweight, and rechargeable electronic earplug. These are ideal for hunting, Law Enforcement, Military Maintenance, Repair and Operation and Military Tactical Shooting. Each earplug is designed to be placed inside the ear and amplifies low frequency environmental listening and serve as hearing protection if a sudden dangerous frequency is detected.
