And I've been looking for real many years later and already determined 50-60 different and also to be as well-known as Final Audio Design Pandora Hope V + VI, Bose SoundLink On-Ear BT, Bowers & Wilkins P5 Series 2, Beyerdynamic, JBL, Devil , Sennheiser, Philips, Audio Technica, Panasonic RP-HD10E-K ... extensively tested. All went back. It has always been missing something. Namely the space. They sounded all not so bad, but for me is the tone at the top. Of course, & geographically it should be. I want to just have the highs as an ordinary thumping, but not too drönenden Bass, the centers should be clear and I do not want only music in the ears hear-I want to feel & the whole head sounded. I hear a lot of electronic music of all genres, as well as classical music and pop. The frequency width of Sony comes to its best advantage when you turn on the ADAC & like me, still uses a high-res player with appropriate music. I have certainly not pro-ears, but hear very much & a very long time music. If I close my eyes and can dream me away, then do the rest of their music and I know these headphones are the best thing that I had always been. They sit firmly and that pads are soft and the many connection possibilities, because many different cable, I can also use my good mobile parts.
