Since I like to sing as a hobby with my husband at home, we wanted to set times SingStar but because the combination packages for too expensive or not suitable songs were often here we have it so bought us separately. The sound is great, the batteries last far still ^^ (about 6 hours of use per week) and it is also not a problem if you stay a little away from the receiver, the sound still very good. So apart from our terrible singing arts). The neighbors rejoice!
