Sennheiser EW 100 G4 Wireless Supercardioid Microphone System

The Sennheiser 509730 is a wireless microphone system that gives singers, presenters, and karaoke enthusiasts the freedom to move while delivering clear, professional-grade sound. At its heart is a handheld microphone that uses a supercardioid pickup pattern to focus on the voice in front of it and reduce room noise coming from the sides and rear. Whether you are leading a band on stage, speaking in a conference hall, or hosting an energetic karaoke night, this system keeps the audience hearing what matters most—your performance.

The handheld transmitter is built with a housing made of lightweight aluminum, so it feels solid without adding strain during long sets. A conveniently placed mute switch lets you step away or converse off-mic in an instant. The companion receiver pairs with the transmitter through simple infrared synchronization, locking in a stable connection in seconds and supporting up to twenty compatible channels when multiple systems share the same venue.

Once connected, the system maintains a reliable wireless link at distances up to one hundred meters, giving performers confidence to roam a large stage, walk through an auditorium, or engage with an audience across a room. Because it can interface with a PC, the EW 100 G4 also fits streaming setups, classroom lecture capture, and content creation workflows that demand consistent, full-bodied vocal audio.

Engineered for daily use, the Sennheiser EW 100 G4 handles the rigors of touring, event production, and fixed-install environments alike. From worship services and corporate presentations to live music venues and DJ rigs, it provides a straightforward path to crisp, dropout-free wireless sound.
