Product Overview
The Audio-Technica EP-C is a detachable 1.6 m (5.2') replacement cable for the E-Series in-ear monitors. It uses A2DC (Audio Designed Detachable Coaxial) connectors at the earpieces and terminates in a 3.5 mm (1/8") stereo mini-plug. The A2DC interface provides a secure, rotation-resistant connection suited to stage and studio monitoring. The cable is compatible with the ATH-E40 and ATH-E50 in-ear monitor headphones.
Product Description

The Audio-Technica EP-C replacement cable is the OEM detachable lead for engineers and performers running E-Series in-ear monitors. The A2DC connector is a coaxial detachable standard that locks securely at the earpiece and resists the rotation and pull that can degrade lesser connectors during a performance. The 1.6 m length provides enough reach for a body-pack receiver or front-of-house bag while remaining manageable on stage. A 3.5 mm stereo mini-plug terminates the cable for connection to in-ear monitor systems, audio interfaces, and portable devices. Maintaining a spare detachable cable is essential for monitor rigs, since a damaged lead can otherwise sideline an entire IEM. The cable fits the ATH-E40 and ATH-E50 without adapters. For additional in-ear monitor cables and accessories, browse the catalog at Creation Networks. Confirm that your monitors use the A2DC interface before ordering.
