Due to the many positive reviews I decided after a long search for these headphones. In addition, they were very low at just under 20 euros. Because they cost originally 40 euros, I am also expected better quality. Today, the headphones arrived and I must say that I am shocked by the sound quality. Each supplied headphones with mobile phones or MP3 players provides a better sound experience. I've tried all the settings on the iPod, the sound was tinny consistently no better. For testing I have the headphones then connected directly to an Onkyo receiver, also here were minimal improvements are made solid. Only at the highest level Bass was a certain balance to guess the sound. Now I wonder because of the many positive reviews that the digits after SHE 9000 / XX make the difference here. I doubt that the flavors can be as different and other users of the headset can be so wrong. The me externally supplied headphones hot SHE 9000/10.
