The only real flaw is the botched operation. The menu is still, however, to have to enter the menu to a key 2-3 seconds and hold:
There is no quick keys on which one can reach frequently used functions quickly. (Eg EQ / Loudness / display dimmer ... etc)
While there are many buttons, but most are with such functions assigned as "back in the menu" or "display" - but this really is only there to switch between time display and title / album display back and forth.
The Menu button must be to enter the menu, hold down 2-3Sek. Another function is not the menu button.
As I said, ansich the device is super.
Radio reception is also surprisingly good (much better than my old Sony the radio), but the user interface is a disaster. The developer must have been drunk. Therefore only 3 stars.
