Powered by the latest DECT7 wireless technology, the APX377 connects you to team members in full-duplex conversation, just like a conference call. No delays, no buttons to push and no clipping or interference. Multi-channel capability lets multiple teams operate simultaneously in the same work area. Push-to-talk or monitor virtually any portable two-way radio via a direct-wire cable connection (wired portable radio adapter required, radio not included). Noise cancelling and auto-leveling microphones ensure you are heard clearly as you move from low- to high-noise areas. Stereo Listen-Through situational awareness lets you hear your surroundings and have face-to-face conversations while protected from dangerous noise levels. Watertight and verified and validated to perform in extreme environments, the APX377 protects your hearing while you get the job done.
