The Cowon iAudio 9 is packed with a nice bunch of features. It has a really nice UI which is easy to use. It has a slight learning curve which can get you thinking at first, but after a few minutes of use, you will easily find your way around it.
The UI has nice graphics and is very responsive. It can be navigated using the slider button in the center. You can browse through music, video, pictures, documents, recorder, flash and settings in a single swipe.
You can navigate through your music collection by artist, album, songs, genre, playlists etc. You can bookmark your content and access it later. You can also use the equalizer, shuffle the songs, repeat tracks and view track info on the Now Playing screen. The iAudio 9 also supports lyrics using the Jet Audio application. It comes with both the MTP and the MSC transfer protocols so you can either just plug it in to transfer data or use it with an MTP interface software.
The iAudio 9 also supports video playback and can play XviD and WMV files directly. It supports the MP3, WMA, WAV, FLAC, OGG and APE audio file formats. It comes with the BBE sound enhancement feature, and this clearly improves sound quality. You can create playlists on the player, or use Jet Audio to create one.
It comes with support for Flash Lite so you can play compatible games and apps on your iAudio 9. You can also view images on your iAudio 9 in a slideshow and set them as the background. It also has a built in speaker, voice recorder and FM radio with recording capability. You can also read text files on the iAudio 9. It also allows you to sync Audible files on the player. However, you get just the bare basics bundled with the player: earphones, USB data cable and the user manual.
