On the face of the Zen X-Fi you find the navigation buttons that is laid out in a 3 x 3 grid and two additional buttons on above and below. The buttons on top and below are clearly labelled with an icon behind the clear plastic.
On the back of the unit is the power switch that also slides to a locked position to prevent accidental power on/off. The body is moulded with a lightweight
metal, most likely aluminum, and left in a natural (Eds note: Thanks to the feedback of a user I upon further inspection (I took out a knife and scratched the casing) note that the material is indeed plastic not an alloy) plastic and finished in a neutral metallic silver colour. Notice the small cut out on the bottom edge, this is the sound outlet for the built-in speaker. The sound from the speaker is acceptable. Vocals came out pretty good but don’t expect any kind of bass response.
On the top edge you find the small cutout for the built-in microphone and the SD Card slot for expanding the 16GB storage capacity. If you don’t plan on using the SD Card slot it comes with a dummy placeholder to keep out the dust and critters.
On the right hand side you will find the reset button (it is recessed to prevent accidental resets), a USB port for charging and transfers, 3.5mm headphone jack and a small green power led indicator.
The Zen X-Fi is small enough to be carried and perform navigation with a single hand. For larger hands the concern will be pressing the small round buttons.
