the U3 only played video files at up to 15 frame/s with a resolution of 160x128. Most videos must therefore be converted to be played back on the U3 using the provided software from Cowon. The player can also display JPEG and TXT files. The support for audio files was also enhanced from previous models: the U3 was the world's first Flash-based player that was able to play FLAC files (but only from compression rate 0 to 2 with the initial Firmware v1.11. It now supports up to Q8 with V1.13). Another new feature was the U3's powerful sound output of 30 mW per channel (at 16 ohm, achieved by utilizing the new Telechip TCC770 audio chipset and Cirrus Logic CS42L51 Codec). Like the U2 the U3 had a built-in lithium polymer cell for a playback time of up to 20 hours. As with all iAUDIO devices, there was no need for the use of software, since the U3 was a UMS device (though additional software was required to take advantage of some features, such as converting video to the right format to be played back on the player). With the firmware version 1.20 Cowon added ID3 browsing and DRM capabilities to the U3. This made the U3 the first iAUDIO player that allowed the user to browse its contents by the contents of ID3 tags embedded in the files.

It was the first digital audio player to feature a 0.85-inch (22 mm) hard drive. This technology allowed the production of a high capacity digital audio player in a very small form factor. iAUDIO T2 In August 2006, Cowon released the iAUDIO T2. The T2 was a necklace type audio player. It featured a color screen, though it did not support video or photo viewing. Features included FM radio, voice recording and Cowon's traditional wide codec support: the T2 supported MP3, WMA, Ogg, and WAV audio files. FLAC was supported up to
