## Overview

Surefire EP4 Sonic Defender Ear Protection offers a 24dB Noise Reduction Rating with innovative filter caps that balance hearing safety and situational awareness. Designed with soft, triple-flanged stems and patented EarLock retention rings, these hypoallergenic earplugs provide all-day comfort and a secure fit under helmets, masks, or hats. Made in the USA from durable medical-grade polymer, the EP4s are reusable and ideal for professionals seeking premium noise protection without sacrificing clarity.

## Description

EP4 Sonic Defenders Plus protect your hearing without interfering with your ability to hear routine sounds or conversations. Their triple-flanged stem design fits larger ear canals and provides a Noise Reduction Rating (NRR) of 24dB. Sounds, at safe levels, are allowed to pass through into the ear canal, while potentially harmful noises (above 85dB) are reduced via a proprietary design that incorporates a special noise-reducing filter. EP4s include attached filter caps, which can be inserted for additional protection and blocking out lower-level noise, like that heard on a plane, where hearing ambient sounds or conversations isn't critical. Right/left color-coded Sonic Defenders Plus are made from a soft but durable, hypoallergenic polymer that provides all-day comfort and an extended product life (up to 6+ months, depending on usage and care). Their patented EarLock retention rings lock the earplugs in place, while soft, adjustable triple-flanged stems provide secure seals in the ear canals. A low-profile design means EP4s can be worn while wearing a helmet or mask, or while using a phone or headset. Available in clear, black, or orange. Comfortable EP4 Sonic Defenders Plus also serve as earpieces for compatible radio communication systems simply by removing the noise-reducing filter and attaching the earpiece to the system. NOTE: EP4 earpiece no longer provides hearing protection once the noise-reducing filter has been removed.

Review: Sitzen sehr Gut - Klein Passen gut ins Ohr und Machen entweder komplett dicht oder nur Halb dich wenn man sie Offen Trackt. sehr bequem Und tun ihren Job und schützen sehr gut das Trommelfell vor Lauten Geräuschen und Knall Geräuschen
Review: i tappi da lavoro definitivi - il meglio se si vogliono dei tappi da lavoro che vanno indossati spesso. calzano molto bene nell’orecchio e sono eccezionali contro i rumori forti, se si vuole ascoltare il collega o una qualsiasi cosa, basta aprire il tappino rosso e il rumore passa (sempre e comunque attutito). costosi ma eseguono il loro egregiamente. [se siete militari ve li consiglio siccome se prendete il cavo che si adatta alla prr con l’uscita non in cuffia ma con l’auricolare, questi sono compatibili, un filo scomodo sull’orecchio che usate per ascoltare le comunicazioni siccome vi esce un filo fuori dal padiglione auricolare siccome il cavo vi tira il tappo verso il basso, ma nulla di preoccupante, comunque una alternativa consigliata a quella cuffiettina schifosa della naja]
