Offered to my husband to replace her old walkman whose memory became insufficient Product me so much that I offered the same (buy on the sony site because I wanted it in black). Replace my Cowon J3 which I have the greatest difficulty in separating me but beginning to show serious signs of fatigue. The Sony meets my criteria: excellent, very good battery life (although lower J3), large storage space (SD card) and pleasant interface. I wanted an mp3 player only dedicated to the music without an internet connection that is synonymous with loss of battery life, but I could easily connect to my Bluetooth Hi-Fi system. I also wanted to transfer my music quickly and without the use of third party software. Finally I find it aesthetically very successful.
