The overall design of the irock! 730 is very effective. A rocking button on the front allows the listener to easily scroll up or down to the next/previous track. Instead of using a volume dial for control, two separate buttons are used. There is a removable clip on the back of the player, which lets the listener clip the MP3 Player for convenience during a jog. Weighing in at 1.1 ounces, it is very light; so it won’t feel uncomfortable in your pocket. As far as readability goes, the blue back-lit LCD illuminates the screen well and can be set to stay on for 3 seconds and longer. The LCD shows ID3 tags, battery life, MP3i compatibility as well as pictures, lyrics and biographies.
