The black N-Pulse Over-Ear Headphones by Monster are designed for DJs with earcups that swivel to the side, but also up and out of the way. They also feature a ControlTalk Universal remote integrated on the tangle-free cables. Additionally, the N-Pulse headphones feature an LED Light Drive for energy-efficient illumination and style. The On/Off switch is on top of the battery box, which is located on the headphones cable. Two AAA batteries are required to power the Light Drive system.
