So obviously the reputation cowon am, the sound is excellent EQ are niquel blah ... And the only major defect of this product is the resistive touch screen, sometimes very little precise (we click the top of the artist we wanted) and request an affected finger (explained on the original protective screen) particular. However this type of touch screen has an advantage! It does not account for the rain! or indeed a smartphone is unusable in the rain or SMS are not typed correctly (at least with a Lumia 900 ...) you can navigate the cushy. Eventually over time you get used to the screen and here is worse. Very good product. I recommend to those who are not too demanding on the touch.
