Earphones and Flying

Until recently I have had a pretty intense fear of flying.  This is very problematic for me because I do a lot of travel for work, so I was very happy to discover Shure E2C earphones.  You may be wondering what earphones have to do with a fear of flying, but let me assure you that with these in (they are basically ear plugs with a music pipe through them) since it kills 90+% of the sound, the experience is completely changed.  I find that I sleep right through turbulence, for example, whereas before I would grip my seat and sweat.
