I am trying to decide between the ATH-ANC7B and the ATH-M50 for listening to music and noise cancelling (active or passive) on an airplane ride between the US and India. I have heard that the noise cancelling really lowers the quality of the audio. Also, I have never used neutral headphones (I know the ATH-M50s are) and am not sure if I would like them or not.
Can anyone give me some recommendations on which you think would be better overall to use on an airplane with all the jet engine noise? I don't want to go deaf after listening for 25 hours of being on the plane.
