This product is intended for airborne sports where there is a need of radio communication in high noise environment but also is required to use a helmet. NC-300H headsets is dedicated to NG-100 helmets series. They have been developed based on our aviation headsets model NC-300. They are available in two versions of mounting - version based on the hinged wire holder ("click" type mounting ) or using flat steel bands mount to the helmet by means of a single screw (rigid mounting). The first one allows to separate shells from the head during breaks in flight. The second one has no this functionality but keeps the shells strongly on place especially during overload or strong gusts of wind. The "click" type recommend to recreational flying, rigid for high performance flight.

Headphones NC-300H are equipped with a hybrid microphone boom – the wire frame connected by a hinge to gooseneck. This combination is high resistant to breaking. Furthermore such design allows a wider range of adjustment which significantly improves the ability to properly adjust the position of the microphone. Attaching the microphone boom to the body provides a metal collar with pressure adjustment. The microphone boom rotates 320º angle and allows a shell with the microphone mount on right or left helmet side.
NC-300H is equipped with a standard gel earpads. Located inside semi-liquid silicone ensures a perfect fit to the head. "Gels" is the only reasonable solution for people who want or need to wear glasses - their elements will not be hurt at the site of contact with the earpads. More than that your package includes soft, made of cotton overlay material mitigate the effects of prolonged contact of skin with an airtight surface of the gel inserts. Color overlay material is chosen randomly.
NC-300H has passive electronics, which includes speakers with frequencies of response 20-17000 Hz, and a high-class microphone with noise compensation (electret or dynamic). One from the ear shell is equipped with a volume control, the second one has built-in PTT (Push-to-talk) button. Headphones have additional shielding protecting against electromagnetic interferences generated by eg. the ignition system of the internal combustion engine.
