Sing and dance to your favorite songs with your friends with the JBL PartyBox 310 + Wireless Microphone Set. You can listen to music for 18 hours with the speaker, which makes it possible to effortlessly party all afternoon and evening. The built-in light effects move to the beat of the music and add extra atmosphere. Because the 2 microphones are wireless, you can stand up to 30m from the box. This means you have a lot of freedom of movement to keep dancing. The microphones have a built-in 'shock mount' system that dampens the vibrations, so you can give the microphone to someone unnoticed. Thanks to the built-in pop filter, you won't hear other noises, like breathing or sharp letter sounds. So the sound coming from the microphone is always clear.
