You can't hear it when the music is playing which is good, but it is kind of annoying because I have to unplug the CD player after every time I use it to get rid of the buzzing noise.

The only complaint I have is a constant buzzing noise that never goes away even when the unit is turned off.

Only problem is the loud buzzing noise it makes just being plugged in, not even turned on
