The clix distinguishes itself through its large display while maintaining a small form factor. A high quality screen made from AMOLED technology produces brighter and sharper colors than traditional LCD equivalents. Controlling the clix is accomplished through iriver's patented D-Click System which involves clicking around the edge of the screen to navigate the menus: touch the top part of the screen to move the menu up, touch the left part to move back a level, etc.
iriver has made the clix compatible with most of the major formats such as mp3, WMA and OGG, and also supports Digital-Rights Media (DRM) protected music. As a result the clix gen 2 supports both subscription model services such as Urge, as well as straightforward purchased music.
Another feature that distinguishes the clix is the video playback capabilities. Playback is limited to mpeg4 which requires videos to be converted to the proper format, but once converted and loaded the player handles the files fine.
The clix supports a stripped down version of Flash that is mainly used for games, but can also be used to install productivity applications such as calendars and address books.
