   Hello,   
      
   My son just bought a new pair of Bose Headphones, the "SoundTrue" model.   
      
   Their .pdf manual says the Plug is 3.5 mm and also 1/8 inch.   
   Obviously, it can't be both, as their is a "meaningful" diameter   
   difference (0.0057) beteen these two dimensions.   
      
   I used to remember that there was always a bit of a problem, as some   
   Plugs that mfg's used were 1/8 inch, and some were 3.0 mm (not 3.5 mm).   
      
   The reason I'm asking is that when he plugs it into our (old CRT style)   
   Panasonic TV audio output Plug, it wiggles a lot and does not make good   
   contact.   
      
   Can someone who is a lot more knowledgeable about these kinda plugs and   
   jacks perhaps straighten us out on all of this. (are there adapters ?)   
      
   Also, the Plug seems to have 4 electrical sections.   
   Have never seen one with more than 3.   
   What are (each) of them for, please ?  Diagram anywhere ?   
      
   Would be most appreciative for your help.   
      
   Thank you very much,   
   Bob
