The quality of this case belies its price, excellent fit and does not get in the way of the units operation.
One operational bug of the X Series Walkman is with the HOLD function, you can selection the hold function to disable all functions, volume, play, next track and Home key . Or, disable just the touch screen function. I disable just the touch screen function so I can alter the volume on the move and use the play/forward/back function. The only problem is the HOME key is also the power-off key. So, if you carry your Walkman in your trouser pocket you have every chance of your unit switching-off because the HOME key has got pressed in your pocket. This case overcomes his problem.
