The blue globe-like part is actually gray. It does not turn blue when you turn it on. In fact, when you do turn it on there is barely enough power to see the lights on the ceiling. The sound is alright but not what I would want to hear while trying to go to sleep. The whole unit feels cheap. It feels like if you tough it you will break it. I gave it to my 2 year old grandson to play with. Expensive lesson learned.
