The iriver clix is a micro-size portable media player from iriver with a 2.2-inch (55mm), 18-bit (262,144 colors) QVGA (320 x 240) TFT LCD screen covering most of its faceplate. The player is navigated by four buttons embedded on its sides, and this innovation is called a "D*Click" system. There are also minimal-sized buttons on the sides for power, button lock, volume, and a "Smart Key" for custom purposes.
