The Cardo HJC 4X is a premium integrated Bluetooth intercom built in partnership with HJC, designed to fit directly into the internal cavities of selected HJC motorcycle helmets for a clean, factory-fit finish. Running on Bluetooth 5.2, the 4X steps up from basic two-rider communication to group intercom for up to four riders simultaneously, with a unit-to-unit range of up to 1.2km (0.75 miles) and a group range of up to 2.2km under optimal conditions. Cardo's Live Intercom technology uses a self-healing connection that automatically re-establishes the link when riders come back into range, keeping your group connected without manual intervention on NZ roads.
Audio is handled by 40mm Sound by JBL speakers tuned for the HJC helmet interior, with three selectable audio profiles via the Cardo Connect app and Automatic Volume Control that adjusts output to match ambient noise as speed or conditions change. Battery life is rated at up to 13 hours of talk time, supported by fast charging that delivers up to 2 hours of use from just 20 minutes on the charger. The unit supports charging while riding via a power bank or motorcycle power source, and carries an IP65 waterproof rating, so it handles New Zealand weather year-round without issue.
Natural Voice Operation lets you issue commands hands-free by saying "Hey Cardo," keeping your hands on the bars and your attention on the road. The built-in FM radio, cross-brand Bluetooth intercom pairing, and over-the-air firmware updates via the Cardo Connect app round out a feature set that covers everything from the daily commute to multi-day touring. Backed by a 2-year Cardo warranty, the HJC 4X is the premium choice for HJC helmet owners who want group communication, JBL audio, and hands-free control in one integrated system.
