Overview
Start your career above the clouds with the S1 Passive, a premium passive headset. It features superb passive attenuation that proves itself in daily use with single-engine and multi-engine propeller planes and helicopters.
Sennheiser’s cooperation with BMW DesignworksUSA has not only given the headset its unique design, it has also set new standards in the areas of safety and comfort. With ear pads specially designed for spectacle wearers, a contact pressure that is individually adjustable and a two-piece headband, the headset is always comfortable to wear even on long flights.
