The Bell HP10 RALLY WW features more technology than ever with the integrated ZeroNoise® Wired-Wireless system. The helmet supports both communication technologies, traditionally wired, and wireless, all rolled into one, without any external elements. Everything is seamlessly integrated: connector, wireless module, battery, and even the well-known ZeroNoise® adaptive noise cancelling algorithm. That means that the helmet is still fully compatible with any other intercom in the market. The WW (Wired-Wireless) system switches automatically between the two communication technologies without any intervention or interruption. The military-grade wireless module guarantees super-fast communication and a generous distance range of connectivity
