Sennheiser HMEC26 - Stereo Headset

Description

The Sennheiser HMEC26 - Stereo Headset is a lightweight closed and supra-aural aviation headset with Active Noise Reduction NoiseGard™. The variant HMEC 26-T features in addition the Talk-Through-Function. By pressing the button on the headset a direct communication with the flight crew is possible. The headset can still be worn. The for speech transmission important frequency range will be transmitted through the Talk-Through-Microphones. NoiseGard™ will still protects from ambient noise while the feature Talk-Through is active.
