Cowon iAudio X9 Super Player 16GB MP3 Portable Media Player With 110 Hours Battery Life. The all new Cowon X9 is a great sounding media player, slighly larger than the likes of the J3 but it is geared more towards video just as much as it is music, as such the screen size and packaging is a bit bigger. Size aside the sound from the X9 is simply sublime keeping that magic Cowon sound signature!
