First you must know that to circumvent the limit of volume it is necessary to set the drive on the region "North America". Fortunately it is very easily accessible from the menu: Settings / System Settings / Redo / language / region. Indeed "Europe" implies a limit of the output volume that prevents a noisy environment use (eg transport). You can then fully appreciate the capabilities of this tiny player. I told him a deputy Micro SDHC Card 32GB (SanDisk course) it is perfectly managed which allows me to have my entire music library. Old buttons allow to avoid the pitfall of touch: everything is there: an on / off button that doubles as locking the keyboard; a directional pad and even on the side: the +/- buttons to adjust the volume at any time. The presence of the clip proves a great addition to use! The set makes a little "cheap" and the small size limits the interest of the screen but we buy it for listening to music and for that, it is perfect !! The sound is powerful (in region USA) and of very good quality. To conclude: I highly recommend it.
