This is identical to the H10-30, only it has a coiled 5 foot cord that terminates with a U-174/U plug for helicopters.

Like the H10-30, this high performance noise attenuating David Clark H10-36 Helicopter Headset has an M-1/DC mic, which is the top Amplified Dynamic variety available.

It has a noise reduction rating of 24 dB so you can hear your incoming communication loud and clear. The gel ear seals and "super soft" head pad mould to your head perfectly to help make each flight a comfortable experience.
