The Shure EAC-IFB is an accessory cable designed to connect a set of low-profile Sound Isolating earphones to any intercom system including the company's PSM personal monitor systems. The 46" cable is terminated with a 3.5mm, single-sided mono connector on one end and an MMCX micro-miniature coaxial connector on the other end. A coiled section provides on-air talent and production crew with a wide range of motion and tug-free comfort, even in the most demanding production environments.
