OK.... I'm going to save you a LOT of money. Time. And ear strain.

 

If you have a noisy airplane... Spend the money on a Bose Aviation X  headset. It works.

 

I own a Quietecomfort 2 headset and it is excellent for use on an airliner or in the car. They are NOT equivalent to the Aviation X. Not even close. If I'm flying on a turboprop commuter flight, I still want my X. The NAME on the headset isn't what makes it quiet. In my Lancair, there is no substitute for the Quiet Comfort of a Bose Headset. I bought a Dave Clark without ANR several years ago... Thing hurt my head. So I bought the cheap Telex ANR of the day ($300.00). It worked. But I was flying a lot and it wasn't quite enough. Next I bought the $800.00 ANR Telex. It worked better. But was still a bit of a head clamp after more than an hour or two at a time. Then, I scored a ride in a fellows airplane who had Two Bose Headsets. Not the new X mind you, but the previous models. They where so much better that I had to have one. Then they came out with the X. It's even better. I've got $1,500.00 worth of headsets that I won't wear.... But the old headsets work great in my Cessna 120. It isn't that loud and I rarely fly it for more than 45 minutes at a time...

Pick your poisen.
