Enhanced Spatial Positioning Push-to-Talk (ESP PTT)


Enhanced Spatial Positioning (ESP) untangles multiple audio streams, providing the separation of incoming audio called stream segregation - enabling the operator to clearly hear individual audio sources and focus on the mission.

Designed for dynamic environments and the needs of the individual operator, this PTT was developed to allow users to mentally focus on an individual directional audio source, even if other channels are active simultaneously.


Four distinct audio channels are heard around the user’s head. Operators hear each channel distinctly from Left, Left-Front, Right-Front, and Right. No more stacked audio. ESP PTT is the ultimate Push-to-Talk hub for tactical operators.


Compatible with major radio platforms using detachable cables for each radio type. In addition, the ESP PTT offers modular compatibility with vehicular and air-based intercoms (ICS). Software and firmware upgrades allow for future channel position options, ATAK PTT functionality, and more. Meets MIL-STD-810Gspecifications, IP68 immersion rated 20m/2Hrs. 1-year warranty.
