Groundbreaking Features - Unique Design. Adaptive NoiseGardTM/digital. To reduce ambient noise to a minimum, just press the Smart Update button on your headset. The system then analyzes the actual cockpit noise and generates the appropriate anti-noise signal. The entire procedure takes only four seconds and can be repeated whenever needed. Treble boost control. Integrated treble boost control increases speech intelligibility in cockpit communications, adjustable in three steps and independent for right and left ears - providing customized audio clarity. Bluetooth technology. The Bluetooth wireless interface lets you connect your headset to a cell phone and MP3 player. This means you can make or receive phone calls while in flight, or listen to your favorite music. For your safety, the music is muted automatically when communicating with air traffic control. Wearing comfort. Optimum noise suppression is also a matter of ergonomic design. The better a headset fits, the more effectively NoiseGard™/digital can do its job. Thanks to the collaboration with BMW Group DesignworksUSA, the new S1 Digital also sets new standards in wearing comfort. Special emphasis was placed on functional details that positively influence the flying experience. Pilots can now adjust the contact pressure of the ear cups in three stages between five and seven newtons. This enables them to find the perfect balance between a comfortable fit and optimum noise compensation. Also new are the ear cushions with a soft, flexible zone near the temples to provide extra comfort when wearing sunglasses. The sleek design with metallic elements is rounded off by the attractive shape of the headband and ear cups that is reminiscent of the sweep of a wing.
