Clear and high-fidelity audio
A unique front-and-rear cavity audio chamber together with a steel blind-hole speaker grille produces clear, powerful, and natural sound.

Long-lasting battery
The built-in 1700 mAh high-capacity battery provides up to 14 hours of operation under the 5-5-90 duty cycle.

One-touch battery indicator
LED indicators show power status at a glance, allowing users to check remaining battery capacity with a single button press.

Hands-free VOX function
The VOX feature enables hands-free communication when using an earpiece, removing the need to press the push-to-talk button.

Efficient radio management
The radio can be managed through a mobile application, supporting programming, batch configuration, frequency backup, and other management tasks.

Channel copy and Air Clone
Analogue channels can be quickly copied from another radio, or the TC-446S configuration can be cloned to multiple devices using the Air Clone function.
