First: The device looks nice and plays music from - the important thing is therefore fulfilled. Otherwise, I am highly dissatisfied with the device. I have previously used 5 years an MP3 player from Samsung. The Sony device is clearly new and you should expect something better. None. The play button is small and difficult to palpate, to be front and back of the device to feel the same. Volume buttons are also tiny and the placement of the back / forward buttons is a single joke. While it was known at Samsung by asymmetrical design (and intelligent Elementplatztierung) immediately where to press, an operator of Sony in your pocket is impossible in principle. USB plug protective drops permanently, because he is very loose. On longer bike rides I enjoy listening to several albums in succession - the Samsung jumped after the end of an album automatically to the next. The Sony shuts down. If you activate it again, he plays the same album again and off to the next one only reaches by complicated through multiple menus lurches. For me, it is, after the experience: Sony will not soon again!
