The Raptor Headset is a bone-conduction hearing enhancer designed for shooters and hunters who require a lightweight alternative to conventional digital earmuffs. Raptor uses bone-conducting technology to magnify ambient sounds while simultaneously allowing the use of high NRR foam inserts (NRR 33dB) for hearing protection against damaging noise from sources like firearms or workplace sources of damaging sounds. 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. A combination that can’t be beaten. NRR – 33dB (when paired with included ear plugs). Users hear ambient sound via bone conduction. Micro USB charging cable included.
