Cross compatibility with all major headsets. Easily connect your public safety radio to your headset with no drama. Constant Able is our patent-pending, next-generation push-to-talk (PTT) for two-way radios that unlocks your entire inventory of accessories. No more juggling separate PTTs for NATO vs. PELTOR wiring or electret vs. dynamic microphones; if it fits, it works. Constant Able intelligently adapts to any setup—replacing at least four separate PTTs with a single, rugged, and mission-ready unit.
