6.0 Active Noise Cancellation Mode and Transparency Mode

6.1 Active Noise Cancellation Mode

With Active Noise Cancellation, TOZO NC3 earbuds detect external sounds through an outward-facing microphone and counter them with anti-noise, cancelling them before they reach your ears. Additionally, an inward-facing microphone listens for unwanted internal sounds, which are also negated by the anti-noise feature. [? ? ❌]

6.2 Transparency Mode

Transparency Mode enhances the voice frequency band, improving awareness of your surroundings, so you can hear what's around you without removing your earbuds. Both Active Noise Cancellation and Transparency Mode work best when your TOZO NC3 fits and is worn properly. [?‍♀️ ? ?]

Active Noise Cancellation Off Mode is the default mode.
