Exceptional performance
The Sennheiser ew IEM G4 offers a wide dynamic range and frequency response (25Hz–15kHz), delivering a rich bass and detailed highs that can be further enhanced with custom headphones. A pilot tone stabilises the transmission over distances of up to 100 metres, even in crowded RF environments. The SR IEM G4 transmitter features dual XLR/jack inputs for balanced and unbalanced signals, parallel outputs for daisy-chaining, and Ethernet connectivity, while the EK IEM G4 receiver is equipped with an OLED display for quick access to signal levels, channel selection, and battery status. Advanced features like Mono, Stereo, and Focus modes allow users to tailor mixes to their preferences, providing optimum flexibility for individual monitoring needs. The HDX Compander technology further enhances sound clarity by reducing background noise, ensuring the highest quality audio transmission.

Scalable and rack-ready
The Sennheiser ew IEM G4 system supports up to 16 systems operating simultaneously within the same frequency range, enabling as many as 32 individual stereo or mono mixes. Whether it's for solo performers, multi-band setups, or corporate events, the system's flexible design allows users to start with one transmitter and expand as needed. The SR IEM G4 transmitter's Ethernet connectivity simplifies integration into larger setups, while the Sennheiser Wireless Systems Manager software streamlines frequency coordination. Additional accessories, such as the AC41 Antenna Combiner, make expansion effortless, ensuring the system adapts to growing technical requirements for both musicians and production teams. The Twin version includes two receivers straight out of the box, enabling independent mixes for two performers right away.

About Sennheiser
In June 1945, Prof. Fritz Sennheiser founded the Wennebostel Laboratory, which initially produced measuring equipment. Commissioned by Siemens in 1945, the young company developed the MD-1 microphone, which was launched in 1946. After the development of further microphones, the company was renamed Sennheiser Electronic in 1958. Two years later, Sennheiser introduced the MD 421 dynamic microphone, which is still in production today and still held in high esteem by many sound engineers. Further groundbreaking developments, such as the HD 414 headphones and the classic MD 441 microphone, hugely enhanced the company's international reputation, eventually making Sennheiser one of the leading manufacturers of microphone and headphone systems in the world.

Wireless in-ear monitoring systems such as the Sennheiser ew IEM G4 have transformed live monitoring by eliminating stage wedges – thus reducing feedback – and delivering precise, tailored mixes that allow performers to focus fully on their craft.
