Active Noise Cancellation (ANC)
The STF Soar headphones feature Active Noise Cancellation to reduce ambient sounds, allowing for a more focused listening experience.
- To Activate ANC: Locate the ANC button (refer to the product overview image for button location). Press the ANC button once. An indicator light (often green) will illuminate to confirm ANC is active.
- To Deactivate ANC: Press the ANC button again. The indicator light will turn off.
ANC works by using microphones to detect external noise and then generating an anti-noise signal to cancel it out. This is particularly effective for low-frequency sounds like engine hum or air conditioning.
