DIGITAL S9 Deluxe Noise Cancelling Flex Boom Microphone

Helmet Kit Parts

(21 products)

Build a helmet kit from scratch or repair the one you have. The S9 noise-cancelling microphone is the heart of it — it is what lets a crew chief hear the driver clearly at full throttle instead of hearing the engine.

The drilless mounting kit is worth a look if you do not want to put holes in a new helmet.
