Ham DX'rs don't operate with engines at 2500 rpm on the backside of their
rigs.
Most important in aviation is speech intelligibility with noise. I think
aviation haedsets need not only ANR but compression, as well.

Keep Heil Sound in mind. They are making their first ventures
into aviation headsets. Their primary business has been
communication mikes and headsets plus commerical (ie broadcast
and bands) mikes. http://www.heilsound.com/


Their Pro Quiet Sound headset is going to be a top ranked ANR
http://www.heilsound.com/pro_set_quiet_phone.htm
It is priced for $225. The only problem is that they terminate
their mikes with a minature plug (3.5mm) then use adapters for
whatever radio they are linking to. One could just replace the
3.5mm plug with a .206" plug (ie Switchcraft 480 or 484, with hot
on the ring and gnd on the sleave) or make an adapter with a
3.5mm inline jack to .206" plug.

Frankly Bob Heil might have a far better headset than Bose. Go
through his web site. He started with the Who. The Eagles are
using his mikes.

Try the HC-4 mike element. It has a narrower range which punches
through noise better (500 Hz to 3,800 Hz with 10 dB rise at 2,000
Hz). The HC-5 has a wider range, 350 Hz to 4,000 Hz with 6 dB
rise at 2,000 Hz, which sounds more normal. How many headset
makers offer a selection of mike elements? BTW, he does have an
element just for ICOM radios (low audio).
