It's your time to shine and take over the stage. JBL wireless microphones produce original JBL Pro sound reproduction, which means crystal clear sound with precise details. Your voice sounds better than ever and you can hit even the highest notes without distortion or lag. When it's time for a duet, you'll hear the sounds of both microphones perfectly through your speaker. The microphones work with speakers equipped with a microphone connection, but for the best experience, pair them with any JBL PartyBox speaker. Connect the wireless two-channel receiver to the speaker and turn on the microphones, and you're ready to conquer the stage. The microphones have replaceable AA batteries, which are easy to replace, so you can keep singing until sunrise.
