Sennheiser EW 135P G4 Camera-Mount Wireless Cardioid Handheld Microphone System

The Sennheiser 509753 is a camera-mount wireless microphone system that gives videographers, reporters, and content creators an easy way to capture broadcast-quality audio on location. At its core is the SKM 100 G4 handheld transmitter, which relies on a capsule with a cardioid pickup pattern and dynamic design to keep the speaker clear while reducing surrounding noise. The EK 100 G4 receiver slides onto a DSLR, mirrorless body, or field recorder and plugs in through a standard 3.5 mm output. Once linked, the system remains stable at distances up to 100 meters and keeps working for as long as eight hours.

This flexible kit is a natural fit for press conferences, red-carpet interviews, weddings, corporate videos, and documentary shoots where a wired mic would slow you down. A single operator can conduct interviews, follow walking subjects, or move through crowds without worrying about tangled cables or signal dropouts. The rugged build handles travel, outdoor work, and frequent setup changes, so you can focus on the story rather than the gear.

Setup is straightforward. Power on the transmitter and receiver, select an open frequency, mount the receiver to the camera shoe, and you are ready to record. Because the system belongs to Sennheiser’s Evolution Wireless G4 family, it delivers the reliable performance professionals expect while remaining simple enough for newer users.
