These are the best earphones I've ever had. First of all, they are very well made and the flat cable ensures really sure that they do not tie so fast! The sound is really amazing in combination with my Xperia S. I hear almost only mainstream and Dance / Pop / RnB Bass really clean and the mids and highs crystal clear. I had read the Creative EP630. The supplement to this one is really worth it. In the Creatives you had all 5 steps readjust because the bass has been lost. In addition, these have always caused an unpleasant pressure in the ear. With Sony's not even realize that they have been in the ear! Real Super these earphones, I can only recommend! Buy recommendation!
