This is a Hannah Montana microphone. It allows your child to sing into the microphone, while their voice projects through the speakers of a boom box. It also has a button for your child to push and hold to hear bee bopping and then sing to that as well as audience applause button.
It is a very cute microphone and the kids love it. Hannah Montana is extremely popular.
It is very difficult to find a station that connects with the wireless part of the microphone so that your child can hear their voice through the boom box. If you do find a station, it is has a ton of static and you cannot hear their voice anyways.
You cannot beat the price of $10.00 and with it being so inexpensive, the kids love it even though they cannot hear their voice.
