SENNHEISER HMEC 45-KA-V NoiseGard™ Headset for Pilots
Supraural Active Noise Reduction Headset
The HMEC 45-KA Open Aire™ headset features the NoiseGard® system for active noise
compensation. Ambient noise in the frequency range between 400 and 1000 Hz is effectively
reduced by 10 dB. The excellent sound reproduction is paralleled in its quality by a noise
cancelling back-eletret microphone for clear speech transmission.
Made in Germany, very lightweight, technologically advanced & sophisticated headset - used
for the vast majority of commercial and regional airliners and corporate flight departments.
This model is the HMEC 45 - KA - V which has a plug for the audio and a plug for the microphone and was used in a B-737. It has the ear pads and case with it. It was used last week in a B-737-700.
