My first HiFi headphones not being on a tight budget. After having used them mostly for listening to CDs, streamed audio and my own WAV ripped CDs I dare to say that they are natural, analytical and very comfortable. If I feel I need to rest and take them off it's because they have a relatively high clamping force. I think they have pronounced higher mid/treble. I use a Little ot MKIII tube amp and after tube swapping with some slight difference in sound reproduction the high frequencies are still strong. Not a problem most of the time, very crisp...
