Three years ago, I was given the advise...."If you can afford the Bose....buy the Bose.....If you can't afford the Bose.....buy it anyway".

My wife said: "You spend $1000.00 now or much more in co-pays and hearing aids"............that made more sense.

I talk to some that love the sennheiser and some who bought it and wish they bought the Bose.

I haven't spoken to anyone that wishes they hadn't bought the Bose. Of course they may be trying to justify spending that kind of cash on a headset.
(Like me)

I bought the Bose and never looked back......so I don't know what's out there...but if the Quiet Comfort headset with the U fly mike is TSO'd, I'd probably buy that today......You can also wear it on a deadhead flight and not look like a dork.

Many guys on the MD-11 claim not to need one, but I still find the noise levels high compared to the 727 with Bose. There are probably a few people with the headset for sale and could buy it used.

Place a wanted ad on the bulletin board at AOC. I am sure some DP flier who needs a little more money for xmas will hoc their old one.

I think the Aviation X is/was so expensive because it was the only product they (Bose) had which was TSO'd
