Heavy-duty Noise-reduction Headset (Blue Color)

( MiNi DIN plug series) :Heavy-duty Noise-reduction Headset

This heavy-duty headset lives up to the demand under extremely high-noise environment in air-piloting and car-racing. It is best used in manufactory plants as well.

Built of Acrylonitrile Butadiene Styrene (ABS), the dome of the speaker is hard, durable and heat-resistant. Layers of sponge filter ensure high passive noise reduction level (NRR) of 24dB, which means a reduction of the amount of background noise reaching your ears. The three-layered thick earpad create a seal around each of your ear from the high noise environment.

The electret microphone offers consistent and accurate transmission.

Features:

Double PTT setting: you have one PTT on the left ear shell and the other in the middle of the wire that leads to the two-way radios;

Detachable wire: the wire leading to the radio could be replaced, so that the same headset could work with different radios (with different interface cable replaced);

Fully tested under extreme environment: the headset has been tested in 50 degree Celsius and -25 degree Celsius; it has also passed through a humidity test under 95% humidity and 40 degree Celsius.
