Since it is powered by a single AA-battery, the X-Micro Video MP3 400 is slightly larger than similar flash-based MP3 players in the market. It has a sturdy black rubber coating on both sides that keeps it from getting scratched or stained. There’s a tiny joystick on its faceplate that you can use to navigate through the software menus. There are also three lateral buttons – play/pause, equalization and a special feature button – plus a hold button on the other side, near which a standard female USB port is nicely hidden.
The 96*64 OLED full-color display is kind of small for music files browsing but it still works out fine. However, it’s not big enough for picture viewing – close up shots are better viewed than scenery pictures. The photos are literally viewed as small thumbnails – you’d have to strain your eyes to notice any details in a, say, mountain scenery picture. Video files viewing are an exercise in imagination due to the Lilliputian dimension of the screen.
