Input:
I received this product on January 17, 2014.  Extremely high quality sound - in a cheap headphones packaging.  One problem - it brings out all the bad quality sound from low-quality sound equipment.  You need a very high quality Digital Signal Processing Unit, to get these to sound acceptable - say, the Creative Sound Blaster Titanium.  And an Equalizer - high quality sound processing software.  Otherwise - it sounds bad.

But for well-made, high quality music, with high quality equipment - fantastic.  Best there is.  I tried them first 7 years ago - and they still got it.  Actually I tried their close relatives - the KSC 35.  Those were uncomfortable though - as was well known at the time - these are more comfortable.  The sliding metal frame on top for this one is a little annoying though - steel sliding on steel - so I just leave it extended.
