Surefire Hearing Protection Comply Canal Tips are the official replacements for the disposable memory-foam tips used by EP7 Sonic Defenders Ultra earplugs. When installed correctly and worn as directed, these body-heat-activated foam tips, tapered for deeper insertion, conform to your ear canal and maintain an acoustic seal, providing a Noise Reduction Rating (NRR) of 28dB.* Constructed of ultra-soft polyurethane foam, Comply Canal Tips provide all-day comfort and help reduce irritation and fatigue in the ear canal. Their elastometric cores feature molded-in threading that makes tip replacement (recommended every 2-4 weeks or when soiled) simply a matter of unscrewing the old tip from the EP7s stem and securely screwing on a new one. Comply Canal Tips are available in 3-pair packs or bulk packaging containing 25 individually packed pairs. They come in three sizes-small, medium, and large-which fit correspondingly sized EP7s. Order small tips for small EP7s, mediums for medium EP7s, and larges for large EP7s. *28dB NRR achieved with EP7s stopper inserted into Hocks Noise Braker filter.
