One ear for the show, one ear for the live feed or the director: the IE PRO Mono Cable keeps one ear free for comfortable interaction with your team, the environment or guests. Thanks to its transparent and twisted design, the cable is both elegant and discreet. It combines the two stereo channels into one mono signal and can be used with any IE 100/400/500 PRO in-ear headphones. The cable construction is designed to be tension-safe and can withstand any live situation. Can be worn left or right.
