• Microphone covers: Windscreens and covers that help protect the microphone element.

Before Ordering

• Confirm the helmet make and model
• Identify the current microphone or part number
• Confirm high- or low-impedance communications
• Check the existing boom, mount and wiring configuration

Frequently Asked Questions

What is the difference between an electret and dynamic microphone?

Electret and dynamic microphones are designed for different communication systems and electrical configurations. The replacement microphone must match the helmet wiring, impedance and aircraft communication system.

Can I replace only the microphone element?

In some configurations, the microphone element can be replaced separately. Other installations may require a complete boom, mount or wiring assembly. Confirm the existing setup before ordering.

How do I identify the correct replacement microphone?

Check the current microphone model or part number, helmet model, connector and communication system. Aviation Survival can help review those details before purchase.

Are all helicopter helmet microphones interchangeable?

No. Microphones can differ by impedance, wiring, mounting style and intended communication system. Visual similarity does not confirm compatibility.
