Sony Walkman recently launched two new models but they were rehashed versions of their older two products. There hasn't been a completely new Walkman out for a while now but the A845 changes that. Not only is it a completely new Walkman, it is also the first in India to have an OLED display and the slimmest Walkman player Sony has ever made. It also has another trick up its sleeve and that's noise canceling earphones bundled with the player. But will that be enough to take on the competition? We find out.
