Singing and public speaking require two things: talent, and a wireless microphone. A wireless microphone keeps unsightly wires out of your performance so the focus is where you want it to be. These devices are easily hooked up to speakers via radio transmission and work just as well as a wired microphone. Purchase a wireless microphone easily from one of the many reputable sellers on eBay.
Don't risk tripping when you’re in the middle of giving a passionate speech or getting your dance moves on. Going wireless allows you to pace across the stage or bust a move without worry. Get yourself a wireless microphone and save yourself from all the problems that come with pesky wires.
