Are those Bose headphones *really* worth that kind of money?  Have seen their 
ads, just curious if they are that much better in service on a HF rig than 
other brands.

  Hi Kirk,

  Indeed they are all the way in on both ends & that pesky hum remains. 
  While assuring they are seated well I tried something, which was to 
  have the headphones on and the stereo plug unplugged at the distal 
  end.

  When not connected there was no hum but when I touched the bare end 
  of the plug to the equipment ground the right sided hum showed up. 
  Nothing surprising here but the same hum showed up regardless of 
  which terminal was touched to ground be it tip, ring or ground.

  Interestingly if I touch the bare connector with my fingers, there is 
  no hum whatsoever.

  The plot sickens
