Sonically I think they underperformed. The bass is flat, the centers präsenzlos and the highs too low and tend to Krächtzen. In addition, the efficiency is poor. If I fully turn up my smartphone (Sony Z1) and play with the equalizer, then the volume of the sound is ok and bearable. But for low-power and reserve reasons I want a reasonable efficiency and sound.
The noise from the outside is pretty well sealed off, but the headphones have pretty strong cable noise so quiet passages of creaking and squeaking are accompanied :(
Therefore, there are new headphones!
