A 2 GB and a 4 GB option will be available. The 2 GB W Series Walkman player can hold approximately 470 songs while the 4 GB option can hold about 990 songs.

Endorsed by US Olympic silver medalist Meb Keflezighi, the NWZ-W260 series Walkman player also offers a convenient quick-charge function.

With only three minutes of charge time, the player can run for up to 60 minutes and full battery life is up to 8 hours.
