The unique acoustic behind the dual-filtered HearDefender-DF varies depending on the user’s individual noise exposure. As noise increases, so will the noise reduction rating of the earplug. With this feature and an internal resonation cavity for increased speech recognition, the HearDefender-DF brings value to the problem of industrial noise exposure. It is available in three different sizes and custom-fit styles.
