   0) Why do you think $40+ is expensive for headphones?   
      
   1) there is more to it than that. Ask yourself why the audio   
   stuff at the beginning of "The Conversation" is Movie Science Fiction   
   (Scott Dorsey on r.a.p used to go on about this, to my   
   much-enlightenment ). I have never tried these things because I   
   don't believe they work.   
      
   2) Because that is what people will pay for them.   
      
   Guy I went to college with went to work for Evil Corporation "X", and   
   basically lived on the road for like ten years. Wasn't married, so   
   he was able to save almost everything he made. The point is that these   
   are a "travel" item and people who burn through a corporation's travel   
   budget can offset salary & bonus with such purchases, and the   
   resulting value to them is higher than for those of us who don't.   
      
   That is why the Sky Mall magazine is like it is...
