Description

IMSA S9 helmet kit with helmet speakers — for drivers who want nothing in their ears on a long stint. Cobalt speakers go in the helmet instead of buds in your ears. The digital S9 mic is built for clarity in high noise and optimized for our digital radio packages, and it works on analog systems too. Built and tested by SRC.

What comes in your order

  • Digital S9 microphone — clear transmissions in high-noise cars
  • Cobalt helmet speakers — no ear buds needed
  • Flex boom — set the mic in the best position
  • Straight cord
  • Standard IMSA four-circuit connection
  • Ear buds wired in — only if you choose them below

Choose your ear buds

The kit is $139 on its own. Add ear buds already wired in and the price is added:

  • No ear buds — run the kit as-is, or add buds later
  • Pro Challenger II (Made in the USA) — add $97
  • Semi Custom (Made in the USA) — add $159
  • Custom Ear Buds (Made in the USA) — add $224

All SRC earbuds are Made in the USA.

Fitment

IMSA is a four-circuit system, typically used for road racing and intercom systems. If your car harness is NASCAR (three circuit), order a NASCAR helmet kit instead.

Works great!

Very happy I went with a Sampson Racing radio kit. Voices were clear inside and outside of the racecar! Easy to install too! Int'l buyers just need to expect duties charges from the gov't $$.

Great helmet kit

The integrated speakers and digital mic in this kit are the way to go. Great sound in and out, plus one less plug to accidentally undo. Super fast shipping too.

IMSA S9 Straight Cord Helmet Kit with Speakers

Hello, the transaction online went very smoothly. Shipping was very fast. In fact, everything was so good, I received two of the same kits. :) I need to return one of them as I only paid for one. Please let me know the best way to return one of the kits. Hi Richard- thank you for getting back to us. We will send you a call tag right away. Cheers, SRC

The must have.

Intercom not useful without the helmet set up. Call the intercom the heart, these are the arteries.

Stilo helmet communications

I order this unit to add into my Stilo helmet. It works and fits perfect! Easy install and no extra Stilo to IMSA jumper which saved me money. Great product for any helmet speaker system. The S9 mic on flex boom and speakers offer fantastic communications!

Perfect Fit

I bought this to install in my Stilo helmet as I wanted a standard IMSA cord without the extra jumper. The install was really easy and the speakers fit right into the ear cups. The other major plus was the mic on a flex boom right up to my lips as now my crew can hear me perfect!
