The Sennheiser EW 122P G4-G is a versatile and portable wireless microphone system configured as a complete lavalier set, ideal for presenters, educators, corporate speakers, and mobile production crews. Operating on a globally compatible UHF frequency band, this system is engineered for reliable performance in a wide array of environments, from conference rooms and lecture halls to houses of worship and on-location video shoots. The all-in-one package includes a bodypack transmitter, an omni-directional lavalier microphone, and a compact true-diversity receiver, providing a straightforward plug-and-play solution for acquiring clear, discreet wireless audio without the complexity of a full rackmount setup.

The system's core is the rugged bodypack transmitter, designed with a metal housing for durability and a secure, locking 3.5 mm mini-jack connector for the included tie-clip lavalier microphone. This omni-directional microphone is optimized for speech, offering a natural and clear vocal reproduction with effective suppression of handling noise. The portable receiver is notably compact, often featuring a clear LCD or LED display for monitoring signal strength and battery status, and includes essential controls for channel selection and output level adjustment. Its true-diversity reception ensures a stable audio link by intelligently switching between two internal antennas, significantly reducing the risk of dropouts as the presenter moves around the space.

Designed with user-friendly operation and transportability in mind, the entire system is lightweight and often comes with a protective carrying case for all components. The receiver can be powered by batteries or an included AC adapter, and offers both XLR and 6.3 mm jack outputs for flexible connection to mixers, powered speakers, or cameras. By combining robust RF performance with Sennheiser's professional audio processing, the EW 122P G4-G delivers reliable, high-quality sound in a convenient, portable format. This makes it an excellent choice for users who need a dependable, easy-to-deploy wireless lavalier system that delivers professional results without requiring extensive technical knowledge or a permanent installation.
