I first purchase the Singing Machine months ago, and I was looking for 2 wireless microphones to go with it instead of Using wired ones. If you're singing with a friend DO NOT buy 2 of these microphones because they will not work plugged in at the same time, however id your singing solo, I wouldn't really recommend this either, when I sung the high notes of songs, it would sound cheap and make a slightly weird noise, I also felt like it made my voice sound different and not like me. Overall, I would not recommend this to anyone! If you're looking for a great microphone, honestly, spend your money and get yourself a hot working microphone, it's just worth it. The microphone does not take double A batteries, they take 9V so if you don't have 9V batteries at your house you have to buy some like me. Microphone is plastic and I read other reviews about it feeling cheap, it does, not the best mic.
