I love this player! 64GB storage without differentiating the internal memory card is comfortable. All audio functions are there, the plethora equalizers (4 customizable), ability to play mp4, ebooks, calculator, alarm clock, radio, it does not serve me often but always practical. Audio quality and battery are both BIG highlights of this player. FLAC file with good headphones are a treat, Cowon remains true to its reputation. As for the battery, the announced 110h are not exaggerated, I easily reaches 95 / 100h of autonomy! However, the player is not without flaws: - He plants a few times (it's still uncommon, do not worry) or starts to show Korean characters. A reboot and talk no more. - Transfers are slow! I do not regret my purchase. If you are still septic, look at the net on tests, you'll be set! ;-)
