Anyone who thinks that his specially rendered MP3 files in the highest quality level would not rustle, the was with this headphone been disabused. This headset solves even vulnerabilities beyond 44kHz clearly on - a good soundcard (96kHz or better) condition. For comfort, I had already tried many headphones in a similar price range, but that does not express, is conveniently located, and does almost unnoticeable after about 2-3 hours. Although the headgear looks like artificial leather, but is genuine - otherwise you would sweat after several hours including - but is not the case. ;) Is also positive that you can buy more ear pads, which are also the same as those for the much expensive models from AKG! Note you have to but that these headphones need more power. Subjectively, this effect affects about one-third lower volume. For mobile parts it is therefore not suitable. I use these headphones for semi-professional masters of their own audio recordings in 44kHz-24bit and higher. And, I'm happy :).
