K4 Bluetooth Intercom Headset – Wireless Communication

The K4 Bluetooth intercom headset is the communication unit for the K4 helmet, adding group talk for 2-8 riders over a 500-meter range. It runs a Bluetooth 5.4 chipset and pairs with two devices at once, so it suits riders who travel in a group and still want music, calls and navigation prompts.

Key features

• Group intercom: real-time chat for 2-8 riders within 500 m.
• Dual-device pairing: connect two devices, such as a phone and GPS, and the headset switches between them automatically.
• Noise cancellation: cuts wind and engine noise, so you can listen at lower volume.
• Voice assistant support: works with Siri and Google Assistant for music, directions and calls.
• Simple button controls: adjust volume, skip tracks and choose automatic or manual call answering with gloves on.
• High-fidelity audio: tuned to stay clear over road noise at speed.
• USB charging and LED status lights: easy to top up and check at a glance.
