JBL PartyBox 2x Digital Wireless Microphone, Rechargeable Battery (20 Hours - 700mAh), Clear Voice, Sound, Stable Connection at 2.4 GHz

Clear voice, crisp sound: the cardioid pattern of these microphones provides a warm, clear, and crisp vocal sound that is designed to make everyone sound better on any JBL PartyBox. Minimize all unwanted noises: A shock-absorbing mounting system minimizes the sound of mics going from one hand to the other, while a built-in pop filter eliminates any extraneous breathing noise you don't want to be part of your performance. Easy to use: just plug in and start singing. It's really as simple as that COMPATIBLE WITH ALL PARTYBOX SPEAKERS - From PartyBox Encore to Ultimate, you can use the mics with any JBL PartyBox speaker. Sing all night long: keep the party going all night with up to 20 hours of playtime. (up to 12 hours playback time when using the wireless digital dongle) RECHARGEABLE BATTERY Simply plug the mic into the charging port of the JBL PartyBox when your battery is low. You can continue to use it while charging. 10 minutes of charging will give you two extra hours of playback. Stable 2.4GHz Connection: When using the wireless digital dongle, you have a stable 2.4GHz connection within 30m of the PartyBox. So don't be afraid to go out and work the crowd.
