　　Your

　　JBL PartyBox is cranking out the tunes, and you're ready to join in. Just plug the JBL Wireless Mic Receiver into the Partybox. Turn on the mic and cut loose. And if a friend wants to join in, hand them the second mic. Both mics are balanced by the receiver, so all you have to do is sing that duet, and not worry about setting levels.

　　These rugged mics are ideal for vocals. They're designed to reject ambient sound and is feedback-resistant. And they have a range of up to 32 feet from the receiver, so you and your partner can move around as you sing.
