Due to noise ordinances in Europe, club owners have created “silent discos” where clubbers listen to music through headphones. Rather than use a speaker system, some club owners have resorted to wireless headphones to entertain club goers.
Music is broadcasted via FM-transmitter to the clubber’s headphones. It’s called “silent discos.” The style of clubbing is popular for music festivals, when people want to party long after noise ordinances would allow. Two DJ’s often compete for the listeners, too.
