Using NoiseGard on the MB 660 (active noise cancelling)
NoiseGard is your MB 660's active noise cancelling (ANC) capability, allowing you to block out unwanted background noise and letting you enjoy the best possible listening experience in all situations.
You can use NoiseGard when listening to music or watching a movie, when using the headset to make a call, or even when it's not connected to anything at all to simply block out ambient noise.
You can use the switch on the side of the headset to switch on this feature, as well as to switch between its two basic modes.
Set to ‘0’ – NoiseGard is switched off.
Set to ‘I’ – Adaptive NoiseGard is activated. Adaptive NoiseGard tailors the level of noise cancellation to the volume of the ambient background noise. When background noise is loud, noise cancellation is high - when background noise is low, noise cancellation is reduced.
Set to ‘II’ – Standard NoiseGard is activated. NoiseGard attenuates the ambient noise to the maximum extent.
