Sennheiser HMEC 26-2-1-BV-K-2
Overview
The Sennheiser HMEC 26-2-1-BV-K-2 is a lightweight closed and supra-aural aviation headset with Active Noise Reduction NoiseGard™ professional. It is designed for use in commercial jets. The variant HMEC 26-2-T features in addition the Talk-Through-Function. Direct communication to the Flight Attendant is possible by pressing the button on the headset. The headset can still be worn. A LED indicates if Talk-Through-Mode is active. The important frequency range for speech transmission will be transmitted via the Talk-Through-Microphones. NoiseGard™ will still protect from ambient noise while the feature Talk-Through is active.
