For full disclosure, I was offered a $5 promo credit for writing this review. While I don't like play for pay systems, there is nothing I can do about it. In regards to the CD player, I have it in my office. The sound is very nice, with the sole exception of a slight and intermittent chirping noise emanating from the speaker. As I understand it, this is normal behavior for mechanical CD players. It is this slight and intermittent chirping noise that is causing me to rate this four stars instead of five stars. This CD player has no problem playing MP3 cds. The fact that it can play MP3 CDs is the only reason I bought it.
