We added a video to show that the CD player doesn't skip and the speakers don't crack or pop when the base or drums increase, but this video was shot on an iphone which doesn't have a great microphone, so the quality of the sound in the video does not reflect what this Lego boom box sounds like. It has a great sound and works great. We're not 100% sure the power cable is original, but it's compatible. The radio also works great, but it takes a while for the antenna to tune into the stations. The more you use it, the more accurate it will be. Cheers!
