I have ~5,500 hours on my Bose X. Yes, that many. They have been overhauled once and repaired 3 times, due to broken wishbones and the bottom of the earcup. IMO they are too fragile for GA flying, they can get dropped, jerked off the panel, stepped on, or sat on too easily and they break. The repair and re-TSO is 250$.
The active + passive noise reduction is pretty good, perhaps around 35-40 dB. I think the A20 and Zulu are a couple dB more. The Zulu II sems much more solidly built than the Bose. In-ear headsets are too much work, and no profesional crews uaser them. The other brands just dont measure up to this level provided by the Zulu II and the A20.

I have two sets of the QT Halo's and will not use anything else. I used a set of the Bose X in a buddies SR22 and hated the clamping. The noise cancelling didn't impress me enough to get me to the point of shelling out that much money for them anyway. I'll never go back to clamping headsets (especially in the summer!).
