Has anyone here or AKG K450 headphone users ever had to get or change their headphone cable more than once, well to be honest here I've done so about three times now and soon will be going onto my 4th cable as I am now loosing sound in the left ear.  When I wiggle the wire slightly around the plug on the bottom (the 3.5mm plus) the sound comes back to normal briefly than goes bcak only to the right ear and no sound on the left ear.  This seems to be a on going issue and each cable seems to last be about 3 months or so, which is just unaacptable.
 
My main Q here now is, what other choice do I have, can I get a custom made cable for these headphones eg something more durable and better, as I getting sick and tired of always spending money buying new cables all the time.
 
Help would be appreciated.
