I just bought these earphones. I can not agree on the previous review. The sound quality is superb, excellent, with excellent bass, well shaped strings, sweet woodwinds and percussions clear. So They recreate a sensation of free and surrounding space in Which music is embedded. Further More, I found Sennheiser's packaging of first class having care of any detail. In my Meinunung after, say, Sennheiser IE 60 are really high-end earphones, able to improve the listening.
