Use the player purchased in July 2011, along with the Sony MDR-EX500LP. The sound is exceptionally well and worlds better than for example from your smartphone (Galaxy S Plus). About the battery you need is usually to worry. This means that the running time is incredibly long. To this day, has not changed. Can not remember that I had to consciously times to a charger hang him lately. Most already have enough dubbing via USB from your PC to be able to hear many hours of music again. The video playback is good and runs smoothly but is not without its problems in terms of the format. That he does not play easily everything. Here you have to convert if necessary. The installed apps can forget. Even if he can flash until today is nothing useful on the Internet to find it. This can present smartphones better by far. Is just a "MP3" player. For the pure music playback it is optimal in terms of playback formats. I would therefore definitely buy it to me again and recommend it. However, what surprises me is the price trend. At that time, I had purchased the player for under 200 euros at Amazon! Currently, he is expected to cost about 300 euros, which is definitely too expensive. This has nothing to do with the quality of the player, which is why I also depart no star here.
