Walkman_X_Series
The Walkman X series is a portable music player designed and released by Sony in Japan in 2009. It was marketed as a high-end, internet-enabled model in the Walkman digital player family in 2009. The model debuted in Japan in April 2009, and then became available in North America, Europe, China and also other regions. The Walkman X series was the first Walkman device to feature a touch screen and S-Master digital amplifier technologies.
Only one generation of the X series was released, making up two models: the 16 GB NWZ-X1050 and the 32 GB NWZ-X1060 (in the US, NWZ-X1051 and NWZ-X1061 respectively). A limited version of the Walkman X series was released only in Japan, with a slightly different design and a higher price. In 2011, it was succeeded by the Walkman Z series.
