my wife heard from morning to evening radio plays, mostly in MP3. She has worn a number of CD players in recent years, at some point all could read no more MP3. This Sony has now already about 2 years ago and it is working properly. The sound and volume are good, he works in the garden in hot weather, fog and frost and in the house anyway. Among the other functions (radio reception) I can not say anything, does not use the best wife of all.
