Once the earpiece is connected to your radio or remote speaker microphone and properly secured, it will function as a listen-only device. Audio from your connected device will be transmitted directly to your ear through the acoustic tube.

- Discreet Use: The transparent acoustic tube and lightweight design allow for discreet communication, ideal for security, law enforcement, and other professional environments.
- Comfort: Ensure the ear tip is comfortably seated in your ear. If discomfort occurs, try a different size or style of ear tip.
