The bose is the best headset I have ever owned, I have nearly 3000hrs on mine and it has been used on over 100 different aircraft from the pressurised Malibu I now fly to the permit and open cockpit.
The ANR is first class and with Lithium batteries I get around 80hrs from a set of batteries.
They are light and comfortable with a minimum clamping force. I have tried more headsets than I can shake a stick at and the Bose win every time.
