The RAPTOR is a radical new approach to hearing enhancement and protection. Utilizing bone-conduction technology to amplify ambient sounds by transmitting sound waves through bones in the head to the inner ear rather than through the ear canals. Used purely as an enhancement device, Raptor delivers unparalleled comfort with nothing covering or inserted into the ear canal. Pair it up with your choice of foam or custom plugs and the Raptor provides hearing protection through Walker’s legendary SAC (Sound Activated Compression) and combined with ear plugs the Raptor provides a 33 dB noise reduction rating.  A combination that can’t be beaten.
