The Sennheiser EW 112P G4 is a professional camera-mount wireless lavalier microphone system engineered for mobile journalists, videographers, and content creators who demand broadcast-quality audio in the field. Built around a rugged all-metal bodypack transmitter and a compact camera-mount receiver, it delivers up to 330 ft of reliable wireless range across 1680 tunable UHF frequencies — so you always find a clean signal, no matter how crowded the RF environment is.
Included with the system is Sennheiser’s trusted ME 4 cardioid lavalier microphone, which uses a directional polar pattern and proprietary HDX compander technology to capture crisp, natural speech while rejecting background noise. With up to 8 hours of battery life, infrared one-button sync, and backward compatibility with G1–G4 and EW 500 systems, the EW 112P G4 is the dependable wireless solution for documentaries, wedding films, corporate videos, and run-and-gun interviews.
