The Bose ProFlight Aviation Headset is targeted to the professional pilot community. Bose claims the new headset is the industry’s smallest, quietest and most comfortable ANR headset, though it does not provide quite as much noise cancellation as the A20. Unlike the ear cups that are used for most aviation headsets, the ProFlight headset uses a headband with earbuds, which makes the whole system less than half the weight of the A20. ProFlight weighs only 4.9 ounces. Bose’s StayHear silicone tips promise better comfort than some other earbud-style headsets.
