DeltaGYup these are very easy to listen to -- I often have to take a rest away from the (lack of ) comfort with my Audeze LCD 3 or the very distinct clear sound with the HD800S and my Stax SR007 . The CZ1 is VERY comfortable and musical for want of a better word. Problem is that most people misread the cross feed and so they say these lack all kinds of things which are not lacking if you listen properly.
