Musicians run a considerable risk of damaging their hearing--as do frequent concert goers. This is a gradual and irreversible process, which can lead to poor hearing and other physical problems. MusicSafe earplugs feature special filters designed for musicians that allow you to protect your hearing while still being able to clearly hear the music. MusicSafe earplugs adapt to the shape of the auditory duct for a secure, comfortable fit, and come with two sets of filters: purple for average use and yellow for greater attenuation.
