DMB MP3 projects a clean and simple look through its black and white color, clear lines and simplicity in the selection of materials. It is the first application of an MP3 device to integrate a T-DMB multimedia device. The no-screws back cover supports the clean and simple design. A luxurious image is conveyed through the player’s high-gloss appearance and simplified shape. Environment friendly materials were used and unnecessary coating material eliminated by using injection rather than a spraying technique. Visual recognition is enhanced by changing the LED colors according to the current MP3/DMB mode. Single-handed grip supports 5-way navigation.
