Aktiv støjreduktion (ANC)
The ANC feature reduces ambient low-frequency noise. To activate or deactivate ANC, press the dedicated ANC button. The ANC indicator light will illuminate when ANC is active.
Note: ANC is most effective at reducing consistent low-frequency sounds like engine hums, air conditioning noise, or train sounds. It may not completely eliminate sudden or high-frequency noises like voices or car horns.

You can use the OneOdio A3 headphones in wired mode by connecting the provided 3.5mm audio cable to the headphone's Aux port and your audio source. This mode is useful when the battery is low or for devices without Bluetooth. ANC can still be activated in wired mode.
