The sound is decent, but the CD/MP3 buttons don't work as intended and even how they feel under the finger & how they sound - when pressed, makes it obvious that the unit is cheaply made. The >> and << press and hold does not fast forward normally, sometimes it automatically takes you back to the beginning/end of the track/song. It's a 50/50 chance if you'll be taken all the way back or not. Also after pressing the Stop button and then pressing Play it takes you to the beginning of the CD instead of resuming where it stopped. This may not sound like a big deal when playing a music CD, but it becomes a HUGE problem when playing an MP3 which has many hours on each CD/MP3 and often long audio-books are on them, and to find where you stopped can be very time consumming and therefore irritating. I do not recommend this unit if you are going to use it for MP3 playing.
