The MusicSafe Pro has been developed especially for attenuation of music and is a generic earplug that will fit into any ear comfortably. Alpine MusicSafe Pro is supplied with three different exchangeable acoustic filter sets, that lower sound levels and prevent the user from excessive exposure, whilst keeping the frequency response of the music the same. The white filters offer the lowest level of attenuation i.e. for pubs, bars etc, the silver filters offer a medium attenuation i.e. for Live gigs, Musicians and Clubbers and the gold filters offer a high attenuation i.e. DJs. The filters are totally dependant on your listening enviroment select the filter you need to use carefully to ensure you get the right protection. The ear tips are produced in a durable, flexible thermoplastic polymer. Once inserted your natural body heat allows the eartip to form to the shape of the auditory duct within just a few minutes, which will increase comfort even during prolonged use. Completely re-useable these earplugs should give years of use and occassionally should be washed in warm soapy warm and dried before being re-used this will obviously help with hygeine but also prolong their life.
