Razor Slim Electronic Quad Muffs feature Bluetooth technology with volume control.  This allows the shooter to control the volume of the ambient noise around them separately from the volume of their Bluetooth connected device.  An integrated communication microphone allows for easy communication with others while 4 hi-gain omnidirectional microphones pick up sounds 360 degrees around the shooter.  A compact folding design and comfort headband with metal wire frame make the Razor Slim Electronic Quad Muffs some of the most advanced hearing protection on the market today.
