I myself am a musician and have many years in this regard a lot of experience with headphones and sound quality and attach great importance which is why I was very skeptical at this purchase as well. These headphones are really good as far as the sound. They are very bassy which I very much like very much. However, I do not find that the heights come up short. I have an in-ear-system for stage performances of Ultimate Ears and therefore good comparisons. For live performances, I would not use them, would look very funny, first and second, the things have completely different frequencies in-ear systems as quality. For any other audio issues but they are perfect !!
In addition, each person has a different ear and perceives music differently. Therefore, I advise all those who interessien for these headphones: ordered them and listen to the sound itself to.
Oh This is still that they fit very well and the processing is brilliant.
Many Greetings
