The Sennheiser ew 100 G4-ME2/835SA1 is a versatile wireless microphone set from the entry-level evolution wireless G4 100 series, operating in the A1 frequency band. This set provides two microphone options in one package: a discreet omnidirectional lavalier microphone (ME2) for clipping onto clothing and a handheld transmitter with the cardioid dynamic MMD 835-S capsule for vocal use. The system includes a single-channel rackmount receiver that can work with either transmitter, offering flexibility for presenters, vocalists, or performers who may need different microphone styles for different segments of a presentation or performance.

The system incorporates core G4 features such as a true diversity reception system for reliable signal transmission, an easy-to-read backlit display on the receiver, and an intuitive setup process with automatic frequency scanning. The handheld transmitter is powered by two AA batteries, while the bodypack for the lavalier uses a single AA. This set is an ideal and cost-effective solution for corporate AV, education, houses of worship, and smaller live sound applications where reliable wireless audio and presenter flexibility are required without the need for the advanced features of the higher 300/500 series.
