Phonak Serenity Choice Shooting & Hunting reusable earplugs are designed to protect the ears from peak sound pressure level caused by hunting and shooting, explosives and fireworks. The earplugs reduce the sound of gun shots, artillery fire and explosions to safe levels making it less likely to cause long term hearing damage. The filters are ANSI IPIL (Impulse Peak Insertion Loss) certified up to 166dB and allow sound directionality and spatiality when no sound peaks are present so users can still hear all low-level noises surrounding them. The earplugs provide an open air passage to the ear keeping the ears ventilated at all times and minimising occlusion effect. The earplugs include hypoallergenic ear tips that are made from medical grade TPE. The product is available in small(5-10mm), medium(6-11mm) and large size(7-12mm) and includes 1 year warranty.
