2. Environmental Listening (Talk-Through)

The Comtac earmuffs feature an environmental listening function, also known as "talk-through," which allows you to hear your surroundings and engage in face-to-face conversations while still being protected from loud noises.

• Microphones on the ear cups pick up ambient sounds, which are then reproduced inside the earmuffs.
• When a loud noise occurs, the system instantly reduces the volume to a safe level, then restores normal listening once the hazardous noise subsides. This compression technology ensures continuous situational awareness without abrupt sound cut-offs.

3. Two-Way Communications

For models equipped with communication capabilities (e.g., single or dual comm variants), the headset allows for clear, intelligible two-way audio communications via radios and intercoms. The Hearing Defender variant can be upgraded with communication downleads and boom mics (sold separately) to enable this functionality.
