Note: If the electromagnetic interference signal is strong in your area, it may affect the Bluetooth connection, and the earbuds will be silent or disconnected, please reconnect it or change the place of use.

Active Noise Cancellation Mode (ANC Mode)

With Active Noise Cancellation, an outward-facing microphone detects external sounds, which your TOZO NC9 earbuds then counter with anti-noise, canceling the external sounds before you hear them. An inward-facing microphone listens inside your ear for unwanted internal sounds, which your TOZO NC9 earbuds also counter with anti-noise.

Transparency Mode

Transparency mode can enhance the voice frequency band and improve the perception of the surrounding sound, so you can hear what’s going on around you without taking off the earbuds. Active Noise Cancellation and Transparency mode work best when your TOZO NC9 fits well and wearing correctly.
