This walkman is perhaps the only market to balance playing many formats, micro sd card slot and worked aspect, both in the design and in the software interface. I am therefore especially pleased that he has no competitors in this price range. However, many disappointments were found after the purchase. Above all, the finish remains well below many ipods I've used. It is assembled in large plastic part, and the buttons are a little cheap, especially the hold switch (which has no visual cues to identify instantly if it is locked or not). Another stumbling block, the audio quality. This is good, but not really on top of the above-named ipods. The sound appears to be slightly more distant in terms of first impressions. However, this is offset by a rather large and pleasant sound space. The sound mainly has the drawback of not being analytical (ie as faithful as possible), and hue of a certain warmth that is nice but somewhat dilutes the treble. I allow myself these observations because without technician I realize these plays on headphones klipsch x11 excellent, from flac files. Finally, although the battery is good continuous audio playback, I would say the sleep mode is less efficient than the competition for use as a daily hour, I had to reconnect the device after ten days, which is only a small increase (about 25%) compared to my previous devices.
I also accuses Sony of dragging persistent defects for years (since the software date at least 5 years), such as the fact that reading does not pause when you unplug the headphones (almost all readers world have this option), and especially that the transition from one file to another generates swings (one second) very noticeable in the reading of an album and spoil the listening experience. Even products not "gapless" are not as bad on that! The interface is nice, but when her significantly less ergonomic than the apple products. Unable to pause outside the example playback screen (though it y has buttons on a small object!).
___________ In conclusion, I do not expect to have so many complaints on a rather high-end device (for the general public and in its category), while my last player had almost 6 years and significantly fewer defects. However, there is no other audio products that could contain more than 50GB (100GB or more) of music in different formats and in a small space, all with honorable finishes and an interface that pleases the eye - and especially less than 250. That is why the note that I attribute to it is also high, though I expected more in 2014.
