JBL PartyBox Wireless Mic (2)

Make your next party or event extra memorable with the PartyBox Two-Person Wireless Handheld Microphone System from JBL.
The set consists of two handheld microphones and a dual-channel
receiver that plugs into the 1/4" mic input on your JBL PartyBox Speaker
(available separately). Each microphone features an electret-condenser
capsule for a clear, detailed vocal sound while the cardioid pickup
pattern focuses audio capture on the singer—helping to reduce potential
feedback issues. The dual-channel receiver automatically mixes both
microphones together with almost no latency, making duets fun and easy.
The mics and receiver both run on built-in rechargeable batteries; the
mics will operate for up to 20 hours, and the receiver will operate for
up to 12 hours on a single charge.
