Frequently Asked Questions

What is an electret aviation microphone?

An electret microphone is a powered microphone element commonly used in compatible civilian aviation communication systems. It is not interchangeable with every dynamic or military microphone configuration.

How do I know which replacement microphone I need?

Start with the part number on the current microphone, the helmet or headset model and the aircraft communication configuration. Matching the existing microphone type and wiring is important.

Are the M-7A, M-7/DC and M-5 microphones interchangeable?

Can I replace only the microphone element?

Some installations allow the microphone element to be replaced separately, while others may require a complete boom or microphone assembly. Review the existing setup before choosing a replacement.
