HearDefenders® Dual-Filters (DF) (Replacement for Custom-Fit Earplugs)

These filters provide variable attenuation – as the nose level increases so do the noise reduction.  Until now military, law enforcement or even coaching staffs were never able to purchase a multi-functional dual acoustics filtered earplug that was designed to help you hear speech better in noise – now you can!   The HearDefenders®-Dual Filters (DF) clearly demonstrates the ability to hear critical sounds better while suppressing unwanted noise.  (Sold in sets – Left Blue, Right Red)
