HMEC 322 is the pilot’s headset designed by Sennheiser especially for noisy cockpits. Medium- and high-frequency ambient noise is passively attenuated by the headset’s closed design and the circumaural ear coupling. Noise – especially in the low-frequency range – is effectively reduced by switching on the active electronic noise compensation of the NoiseGard™ system. Altogether, this guarantees clear communication and stress-free flying without fatigue. The volume can be regulated directly at the headset. The boom of the noise-compensated microphone can be flexibly adjusted and swivels through 270°, allowing it to be worn on either side. A special connector ensures the correct polarity in any helicopter. In terms of comfort and versatility, this headset, also in the HMDC 322 version with a low-impedance dynamic microphone, is ideally suited for tough, everyday use. A version with variable impedance is also available.

Both HMEC 322 and HMDC 322 come with coiled cable and U174/U connector.

HME120 is the pilot’s headset for superior noise protection and comfort in helicopters.

Effective acoustic shielding is achieved by the headset’s closed design, which provides optimum passive hearing protection and efficiently shields the ear from noise. A noise-compensated electret microphone attenuates ambient noise and improves the intelligibility of radio communication. The volume can be adjusted directly at the headset. Soft, padded ear pads and the broad headband make the headset extremely comfortable. For superb wearing comfort even for hours on end. The microphone boom is flexible for easy adjustment.

HMD 120, equipped with a dynamic microphone, completes the model range of this pilot’s headset, which provides a welcome reduction in rotor and engine noise in the cockpit.

KDHC 22 offers the professional pilot integrated safety due to the active noise compensation of the NoiseGard™ system for pilots’ helmets. Especially during rescue operations, stress, noise, possible time pressure and poor weather conditions all combine to produce a risk factor that may have a negative impact on a pilot’s concentration. To ensure that safe communication is not impaired, Sennheiser has also developed an active noise compensation system for use in helicopter pilots’ helmets. A conversion kit specially designed for the GENTEX models SPH-3, SPH-4 and SPH-5 allows the proven NoiseGard™ system to be quickly and easily employed. As a result, low-frequency noise is reduced particularly effectively.
