Purpose-built to bridge the gap between high-fidelity digital intercom systems and specialised open-face rally shells, this kit delivers exceptional audio performance under intense stage conditions. It provides competitive crews with an uncompromised communication link, ensuring every pace note and technical update is transmitted with perfect clarity.\u003c\/p\u003e\n\u003ch3\u003eHigh-Isolation Acoustic Earcups \u0026amp; Tailored Half-Bar Layout\u003c\/h3\u003e\n\u003cp\u003eOpen-face competition environments present unique acoustic challenges, including severe wind buffeting and loose gravel spray. To combat this, this premium kit features heavy-duty, high-isolation integrated earcups designed to fit comfortably inside the helmet shell, heavily suppressing ambient sound pressure levels to shield the driver or co-driver's hearing. This specific configuration is engineered without a traditional trailing microphone flexible boom arm, making it the ideal choice for helmets with structural half-chin bars where a fixed, low-profile microphone mounting is preferred.\u003c\/p\u003e\n\u003ch3\u003eStandardised Paddock Interfacing \u0026amp; Robust Strain Relief\u003c\/h3\u003e\n\u003cp\u003eTo ensure seamless compatibility with your team's existing electronic infrastructure, the kit terminates in an industry-standard Female 4-Pin Nexus plug (Standard configuration). Built to withstand the physical demands of stage rallying and off-road racing, the wiring loom is wrapped in a highly flexible, abrasion-resistant outer casing. The heavy-duty Nexus terminal incorporates moulded strain-relief boots to prevent internal wire degradation from constant connection and disconnection cycles, maintaining absolute electronic reliability stint after stint.\u003c\/p\u003e\n\u003ch3\u003eKey Performance Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eJet Helmet Optimisation:\u003c\/strong\u003e Specially engineered for open-face jet helmets fitted with a structural half-chin bar.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Isolation Earcups:\u003c\/strong\u003e Integrated ear cups provide superior passive noise damping against exhaust roar and wind buffeting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoomless Low-Profile Design:\u003c\/strong\u003e Configured completely without a flexible boom arm to integrate neatly with fixed chin-bar structures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFemale 4-Pin Nexus Terminal:\u003c\/strong\u003e Industry-standard connection ensures plug-and-play compatibility with flagship ZeroNoise amplifiers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavy-Duty Wiring Loom:\u003c\/strong\u003e Ruggedised, abrasion-resistant cabling preserves signal integrity in high-vibration cockpits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced Speech Comfort:\u003c\/strong\u003e Optimised internal speaker drivers deliver articulate voice reproduction to reduce mental fatigue.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ZeroNoise","offers":[{"title":"Default Title","offer_id":54142904959317,"sku":"ZERONOISE-370256","price":213.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1048\/1260\/9877\/files\/zeronoise-rhk-fjh-hcb-female-nexus-4-pin-std.jpg?v=1781597483","url":"https:\/\/shop.spindriftmedia.com\/products\/zeronoise-rhk-fjh-half-chin-bar-helmet-kit","provider":"Spindrift Motorsport","version":"1.0","type":"link"}
