As a former owner of a Cowon J3 me that unfortunately broke, so I threw on this PMP with a large screen but with a medium resolution (480 x 272) but the screen is very good quality and the resolution does not interfere with anything readability. Getting impeccable hand it weighs a little heavier than the J3 (inevitably given the size) and is comfortable in large hands. Level 110h autonomy announced, it should be 80 / 90h in FLAC with a helmet Top range is already larger than the J3 that had a 80h autonomy announced. Audio quality now, Cowon has managed to improve on this and push further the sound quality (which was already huge with J3) and X9 has the Jet Effect 5, the new version so. In short, the music player will delight audiophiles with its handling and its audio quality, and I understand how they pounce on an iPod when you have the competition that much better in the field of audio players. Do you throw it, it's worth it!
