The Sennheiser EW 100 G4-865-S-G is a professional wireless vocal system configured as a complete handheld set, designed to deliver reliable, high-quality audio for vocalists and presenters in a wide range of live and installed sound applications. Operating on a pre-coordinated UHF frequency band within the G group (specific range varies by region), this system provides robust performance with strong resistance to interference, making it suitable for environments such as houses of worship, corporate events, and medium-sized performance venues. The set is centered on a durable handheld transmitter that integrates the Sennheiser MM 865 dynamic supercardioid microphone capsule, paired with a true-diversity receiver, offering an all-in-one, ready-to-deploy solution for critical vocal reinforcement where superior feedback rejection is required.

The handheld transmitter features a rugged metal body built to withstand frequent use and houses the interchangeable MM 865 supercardioid capsule. This microphone is specifically engineered for vocal applications, delivering a detailed and present frequency response with a tighter pickup pattern than a standard cardioid, providing even greater rejection of unwanted ambient noise and monitor feedback. The receiver, available in either rackmount or compact portable formats, incorporates a user-friendly interface with a clear display for monitoring RF and audio levels. Essential features like automatic frequency scanning to locate an open channel and pilot tone-based squelch ensure straightforward setup and stable operation, protecting against interference from other wireless devices in the environment.

Engineered for seamless integration and professional audio results, the system utilizes Sennheiser's advanced companding technology to deliver transparent sound with a wide dynamic range and low noise. The receiver provides both balanced XLR and unbalanced 6.3 mm jack outputs for flexible connection to mixing consoles, powered speakers, or recording interfaces. Sold as a complete package with necessary accessories—including antennae, a power supply, and often a protective case—the EW 100 G4-865-S-G provides a dependable, out-of-the-box wireless solution. It represents an ideal choice for performers and presenters in feedback-prone environments who seek the trusted performance and enhanced rejection of a supercardioid pattern within the accessible Evolution Wireless 100 series.
