16GB Cowon Z2

The device is very beautiful, the hull is well in hand and is not subject to fingerprints.

The screen is of a good quality without stirring.

The operating system (android 2.3.5) is reactive (just under a galaxy S2 android 4.0.4) but does not have the google play store (natively on several internet manipulation are offered to the install).

Reading the various media is done quickly and without jerking (for good quality videos).

Regarding the sound: EXCELLENT, really I rediscovered my helmet and my songs! The supplied headphones sound poor, which is a shame on the part of cowon ...
Several "equalizer" are present, and BBE are for me the best!

The bad thing autonomy to an mp3 player (though it helps make lots of other things), this is really ridiculous, count maximum fifteen hours.
The standby let's also not a good idea, is better turn it off and on again after each use.

A little pricey for just an mp3 player, (because for playing movie / video I find the screen too small, surfing the internet with WI FI is good without being very nice) but the sound quality is really there, and the overall quality of the device.
