I bought these headphones for both listening to music and producing music after reading reviews of them about how they are meant to be very non-fatiguing and detailed, so they can be played at louder volumes without discomfort, as an upgrade for my Sennheiser HD600's. However, I was very disappointed by mine. The treble seemed very harsh and distorted, and the upper midrange actually had a peak around 2.8 KHz, both of which led to music getting quite uncomfortable before even reaching 25% volume on my amp. It seems as if my pair had bad harmonic distortion in the treble, as it basically sounded like harsh and unpleasant fizz in music with a lot of treble detail. Comfort-wise, they are heavy, but the weight didn't bother me at all. The headband does a good job at distributing the weight. However, the seal on the earpads did cause discomfort and pain for me due to the feeling of inequal pressure it causes. No one really mentions this, so avoid these if you're sensitive to very airtight seals and ear pressure changes. I imagine other pairs would sound better than mine, but this kind of quality control on 1300€ headphones isn't acceptable.
