The sound of the machine is wonderful with no static. My niece had it turned up just a quarter of the way and I could hear it outside. The mic comes on nice and clear and the words, when plugged into the TV will show up if using a karaoke CD. She also used her iPod and smartphone to play songs on it. The only thing she didn't like is the CD it came with. It comes with a CD of 35 karaoke songs, but the songs were way young for someone whose 12. (It had songs like On Top Of Old Smokey, She'll be coming around the mountain, Dixie Land, etc)
This karaoke player is very nice. Bought it for 8 year old. She loved it.
