The Countryman E2W5TSR is a versatile unidirectional earset microphone designed for broad compatibility across various professional wireless systems. This model features a cardioid (unidirectional) polar pattern that provides focused front pickup with good ambient noise rejection, enhancing gain-before-feedback in live environments. The microphone is finished in a Tan color and utilizes the comfortable and secure "W5" over-the-ear wire band. Its defining feature is the inclusion of a detachable cable terminating in a standard 3.5mm (1/8") locking connector, which is compatible with a wide array of bodypack transmitters from manufacturers such as Sennheiser, Lectrosonics, and others, offering significant system flexibility for rental houses and engineers who work with mixed gear.

The cardioid pattern offers a reliable balance between audio quality and feedback rejection, suitable for theater, worship, presentation, and broadcast applications. The Tan finish provides a neutral, discreet option for various skin tones and costumes. The W5 band ensures a stable and comfortable fit for extended wear. The detachable cable system is a key feature for serviceability, allowing for easy cable replacement if needed. The locking 3.5mm connector is crucial for preventing accidental disconnection during vigorous movement on stage.

Built to Countryman's standards for durability and sound quality, the E2W5TSR delivers clear and natural vocal reproduction. Its combination of a versatile locking 3.5mm connector, detachable cable, comfortable fit, and professional cardioid performance makes it a practical and dependable choice for performers and audio technicians who require a high-quality earset that can interface seamlessly with a broad spectrum of professional wireless transmitters.
