The SWAT Combat Radio Comm System by EarPro, SureFire's audio products division, makes it possible for a tactical officer to direct incoming radio communications clearly and covertly into his ear, while enjoying state-of-the-art hearing protection/enhancement featuring digital compression technology. The SWAT Combat Radio Comm System's wire kit is built to stand up to the rigors of extreme conditions. Its shielded cable is wrapped in Kevlar and jacketed in thermoplastic urethane for resistance to flex fatigue, abrasion, chemicals and extreme temperatures. It features a weatherproof machined-aluminum inline speaker that delivers a broader range of voice frequencies for crystal-clear communications and a submersible, omni-directional microphone with integrated windscreen for professional-grade transmissions.
