Sennheiser HMEC 250 NoiseGard Pilot Headset
It isn't a good headset for a prop airplane. I tried it once in our Cessna 152 (1979) and the headset was amplifying the noise into my ears. It was really bad. But with noise canceling off, I couldn't hear the tower. I never had a headache after flying till that day.<br />Returned immediately.<br /><br />Sennheiser produces best in the world headsets to listen to music, this one is good for this purpose too. Just spare yourself trouble and don't attempt to fly an airplane with it.
