Bought in May 2013, I use about 1 pm daily, exclusively for listening to music with headphones Sennheiser PX100, mainly WAV format for better quality, but also some MP3. Menu "Folders" convenient to choose his title rather than take what comes with my little like i-pod without screen and sound quality much better than my SanDisc Sansa clip I therefore relegated to only songs in MP3. It had replaced a Sony SanDisc NXZ B15 crashed after a few months and I had much regretted for its musical quality. The Philips GoGear seems the same level as in the Sony sound quality and much more convenient to choose the music. In addition, I have also read that identify FLAC files, known as good quality music as WAV but lighter: that good !! Only a concern to see some comments on its reliability .....
