4.6 Noise-Cancelling
IO-12 headphones incorporate active noise-cancelling
technology (ANC) that can significantly reduce the
disturbance of ambient noises – for example, general city
noise or aircraft cabin noise.
IO-12 active noise-cancelling technology also incorporates
a transparency option that enables ambient sounds to pass
through the headphones unimpeded. Transparency can
enable you to hear conversations or important ambient
sounds without the need to remove your IO-12 headphones.
Noise-cancelling is controlled from a push button on the edge
of the right headphone cup.
Press the button once to engage noise-cancelling and a
second time to select the transparency option
Press the button once again to disengage noise-cancelling
and transparency.
