Features and Benefits

Wireless connection

With the built-in BT 5.0 module, the HM6 Series can work with the BT audio accessories to boost your safety and productivity during in-vehicle communications. And these radios can be programmed through BT, saving time and resources.

Superior durability

The radio withstands harsh temperatures, shock, and vibration, and meets MIL-STD-810H standards, and IP54 for dust and water intrusion. The connection between the palm microphone and 10pin aviation connector keep very tight and is difficult to loosen. The drawstring of the palm microphone has the excellent stretching ability to protect the palm microphone to get the maximum service life.

Crystal-clear audio

The radio delivers superb audio on noisy streets or highways. The AI-based noise cancellation filters out echoes and background noises such as horn and engine sounds, making you hear and be heard in the conversation. The howling suppression prevents the screeching or howling feedback between two radios in the same vehicle, ensuring clear and uninterrupted communication on the move.
