Entel CXR16 Throat Mic for fire fighting
Entel CXR16 is a professional-grade fire fighting throat microphone designed for extreme hazardous environments. It transmits audio through Larynx Vibration Detection, picking up vocal cord vibrations directly from the throat for clear communication in high-noise environments where traditional headsets fail.
The Entel CXR16 delivers reliable throat-based communication for firefighters and hazardous environment workers who cannot accommodate headband-style headsets. Its larynx vibration technology ensures intelligible audio transmission regardless of ambient noise, breathing apparatus, or protective equipment interference.
