ISOtunes Sport Defy Bluetooth Tactical Earmuff

Defy™ is a tactical earmuff that defies every assumption shooters have about painful and restrictive hearing protection. This modern take on a traditional style earmuff features next-generation technology, providing environmental awareness and gunshot noise attenuation.

Tactical Sound Control™ is proprietary technology that amplifies the sounds you want to hear, up to 8x their natural volume, while still protecting you from harmful gunshot noises in under 2 milliseconds. 

Most gunshots register between 150-70 decibels, which can quickly damage your hearing. Combat those dangerous noise levels and shoot safely all day long with Defy.
