1. The shell and cables are made of fire-resistant and flame-retardant materials
2. Use a miniature power amplifier unit to process the voice signal with anti breakage, anti loss, and noise suppression technologies, and then filter and amplify it to drive the built-in speaker to work.
3. First, use high-quality speakers with uniform, balanced, and full amplitude at each frequency point, which can clearly hear the received voice content within 10M. Human machine separation has been achieved within a certain range, releasing manpower.
4. Using military grade professional connectors and low loss shielded wires, the audio signal transmission is stable.
5. The overall design features small size, light weight, easy portability, no need for separate power supply, and plug and play functionality.
6. Features such as waterproof, dustproof, drop resistant, durable, low power consumption, stable and reliable operation.
