This is the preferred choice of many professional pilots. It's an ultra lightweight headset with an incredible on-the-head weight of only 3/4 oz. (21.3 g). The high quality electret mic provides maximum talk power, unparalleled noise cancellation and immunity to 400 Hz hum. The mic-boom is bendable for exact positioning of the mic close to the mouth for maximum speech clarity and an unobstructed peripheral view for the pilot.
