ABOUT HX-920R0: The HX-920R0 is a lightweight and intrinsically safe headset. Wear the reversible headset by rotating the gooseneck microphone for left or right-sided orientation. With a noise-cancelling electret boom mic and a speech-enhancing receiver, every word can be heard crystal clear over the background noise. Single-sided headsets allow Users to maintain situational awareness while monitoring the communication from their team members.

HIGH-QUALITY SOUND: The considered selection of professional microphone & receiver elements in SED® headsets provide best-in-class voice clarity while being used in commercial environments. Unidirectional, noise-cancelling electret boom microphones and the speech-enhancing receiver can greatly highlight voice-over background noises to ensure every word is crystal clear.

What is Intrinsically Safe?

Intrinsically Safe means that the system is incapable of causing an explosion or being a source of ignition in the presence of potentially explosive or combustible materials and gases.  In other words, the equipment and wiring are incapable of releasing sufficient electrical or thermal energy under normal or abnormal conditions to cause the ignition of a specific hazardous atmospheric mixture in its most easily ignited concentration.  OSHA and MSHA have many reports of fires caused by non-intrinsically safe systems.  Preventing fire and explosions is a top priority for all industries around the world.
