IMSA S9 Helmet Kit – Straight Cord, Ear Bud Jack
Description
Description
The IMSA S9 Helmet Kit with straight cord is our core four-circuit road racing kit. The DIGITAL S9 microphone is built for clarity in high-noise environments and optimized for our DIGITAL radio packages — and it works just as well on analog systems. Run your own ear buds through the 3.5mm jack, or add a pair below and we wire them in.
What is in the kit
- DIGITAL S9 microphone
- Flex boom for optimum mic position
- Straight cord
- 3.5mm (1/8") mono ear bud jack
- Standard IMSA four-circuit connection
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.
Other versions of this kit
- Cord that stays off the floor: Coil Cord, Ear Bud Jack
- Speakers in the helmet instead of buds: Straight Cord, Helmet Speakers
- Both speakers and a bud jack: Straight Cord, Speakers + Ear Bud Jack
- Standard mic, lower price: IMSA Helmet Kit – Standard Mic
