The Telex CES-2 is a professional, single-ear audio accessory kit designed for use with belt-pack and panel intercom systems in demanding production environments such as broadcast television, live theater, film sets, and sports broadcasting. The kit provides a clear, hands-free communication solution for directors, stage managers, camera operators, and other production staff who need to receive instructions while keeping their hands and visual focus on their primary task. The earpiece features a discreet, over-the-ear design that holds a small acoustic transducer securely in the user's ear canal, delivering clear audio directly from the intercom system while allowing the user to maintain awareness of ambient sounds—a critical safety and operational feature on busy sets and stages.

The kit is engineered for durability and user comfort during extended wear. It includes a robust, coiled cord that resists tangling and provides ample reach and flexibility for movement, terminating in a standard 4-pin XLR connector compatible with most professional intercom belt packs and panels. The earpiece itself is typically constructed from a soft, flexible material for a comfortable fit, and may include multiple sizes of ear tips to accommodate different ear canals. A built-in volume control wheel or slide allows the user to adjust the listening level directly on the earpiece cable for immediate, convenient control.

As a staple in professional intercom setups, the CES-2 kit prioritizes reliability, audio clarity, and practical ergonomics. Its single-ear design supports effective communication without isolating the user, which is essential for coordinating complex live productions. The robust construction of the coiled cord and connectors ensures it can withstand the physical rigors of daily use in fast-paced, technically demanding environments.
