How to use

Remove the helmet cheek pads or open the speaker pocket to access the original speakers. Carefully disconnect the old drivers from their wiring harness and extract them from the speaker cushions or mounting pockets. Insert the replacement 40 mm speakers into the same locations, ensuring the driver faces inward toward the ear and that the wiring follows the original routing.

Reassemble the helmet padding once correct placement and function are confirmed.

For reliable performance, use these replacement speakers with compatible INTERPHONE headset models and follow helmet manufacturer guidance for speaker placement. Avoid exposing the speakers to moisture or direct impact; if soldering is required, ensure secure, insulated connections and test volume and microphone function before each ride.
