INTRODUCTION We appreciate your choice Congratulations on your purchase of a Bose® Aviation Headset . This headset combines Bose Acoustic Noise Cancelling® headset technology to electronically reduce unwanted aircraft noise, and Bose TriPort® headset technology for a smaller, lighter, more comfortable headset that delivers full-spectrum noise reduction. We believe it is the finest aviation headset you can own. Headset and cable variations The Bose Aviation Headset is available in variations designed for general aviation and helicopter use. There are also battery powered and aircraft powered versions (Figure 4 on page 9). The communications cable for your headset may be either straight or coiled, depending on the headset configuration you have purchased. Features common to most variations: • Acoustic Noise Cancelling headset technology • TriPort headset technology • Communications cable with integrated control module • Flexible microphone boom with continuous position adjustments • Adjustable headband • Replaceable ear cushions • Replaceable fleece headband cushion • Replaceable windscreen • Cable-mounted clothing clip 8
