Designed exclusively for the professional DJ, the DJ1 PRO is the ultimate in style, flexibility and performance. Just like the DJ1, the DJ1 PRO uses our amazingly tough 50mm Mylar driver for lots of volume and bass. Then the DJ1 PRO steps it up by offering detachable cables, speed switch ear pads and a carrying case for your headphones and accessories. For the professional DJ, the easily switch ear pads and cables will save your neck should something happen at a gig. Equipped with MU-Metal shielding, along with the patented S-Logic(TM) technology , these headphones also meet the concerns of DJs and let you spin for hours without worrying about your hearing.
