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. If connected to a stereo signal, only the left signal will be transmitted. It can be used with any IE 100, 400, or 500 PRO in-ear headphones. The cable construction is designed to be tension-safe and can withstand any live situation. It can be worn on the left or right.
