Organize a very musical evening with the JBL PartyBox Wireless Microphone Set. With the 2 microphones, you can invite your friends out for a karaoke evening. The included receiver makes it possible to use the microphones wirelessly up to 30m from the speaker. This way, you have more freedom of movement and you can keep dancing while singing. The microphones have a built-in 'shock mount' system that dampens vibrations. You won't hear the bumps when you give the microphone to someone else. Because of the built-in pop filter, you'll hear a clear sound and not other noises, like breathing or sharp letter sounds. The 20-hour battery life allows you to easily use the microphones for the entire party. is the microphone empty? Charge it in a socket or in the built-in power bank of the JBL party speaker.
