The 3M PELTOR EEP-100 Electronic Earplugs are built tough for the working professional. They help provide protection when it’s loud, but allows you to hear normally when it’s not. Ambient sounds can be heard at a level below 82dB. Improves your ability to communicate with nearby colleagues, as well as hearing warning signals, approaching vehicles, or sounds in machines and processes. Speech and weak signals can be amplified helping to enable face-to-face communication between workers without earplug removal. Ideally suited when there is intermittent, varying and/or unpredictable noise; if you are removing your hearing protection to communicate; where enhanced situational awareness is required (e.g. moving vehicles/equipment are present, alarms need to be heard, for maintenance personnel); or if you regularly move between loud and quiet areas. Applications might include road/building construction, maintenance, general/heavy manufacturing, airport ground crew, forklift drivers, and autobody shops. The small and lightweight design helps improve the overall comfort and user experience and makes it compatible with most head borne Personal Protective Equipment (PPE), such as helmets, hardhats, eyewear and face shields. The earpieces are rechargeable via a micro-USB jack on the pocket-sized charging case. The case also provides easy and convenient storage of the earpieces when not being used. Kit contains portable charging case, 1 pair 3M PELTOR Electronic Earplugs, 1 pair 3M PELTOR UltraFit Eartips Small (23dB), 1 pair 3M PELTOR UltraFit Eartips Medium (23dB), 1 pair 3M PELTOR UltraFit Eartips Large (23dB), 1 pair 3M PELTOR Triple C Eartips (27dB), USB charging cable, and user instructions. 3M strongly recommends individual fit testing of hearing protectors. If the NRR is used to estimate typical workplace protection, 3M recommends that the noise reduction value be reduced by 50% or in accordance with applicable regulations.
