Serenity Choice Music reusable earplugs are designed specifically for musicians and concert or event goers to help prevent hearing damage in loud listening environments. The filters minimise sound to a safe level without affecting the original sound for the listener. Hearing protection is recommended in any situations where noise levels exceed the safe limit of 85dB and music concerts usually exceed this safe limit. Phonak Serenity Choice Music earplugs reduce the level of sound by 17dB, therefore listeners can safely enjoy the music levels as loud as 102dB up to 8 hours. The earplugs provide an open air passage to the ear keeping the ears ventilated at all times and minimising occlusion effect. The membrane filters provide a tuned, flat attenuation response so that all frequencies are reduced by almost the same level without losing anything from the original sound. 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.
