Information on active noise cancellation
ANC
Due to its closed design, the headphones offer effective passive iso-
lation from ambient noise.
In addition, the headphones have an active noise cancellation (ANC)
function, which allows you to reduce ambient noise to a minimum.
Even when ANC is activated, your headphones' sound quality is
always at its best.
You can activate or deactivate ANC when the headphones and your
audio source are connected via Bluetooth, the USB cable, or the
audio cable (provided that the battery is sufficiently charged).
If you want to create a quiet space in a noisy environment, you can
simply use the headphones – without cable and disconnected from
any Bluetooth device – with ANC activated (>
31).
The Smart Control app allows you to select different ANC modes that
offer the optimal settings depending on the application/situation.
For example, low-frequency noise can be suppressed, wind noise
can be minimized or a possible feeling of pressure on the ears can be
avoided.
Notes on active noise cancellation
• Continuous uniform noise, such as motor or fan noise, is particu-
larly well suppressed.
• Speech or high-frequency noise is significantly reduced, but can
remain perceptible.
• In very quiet environments, slight noise may occur. In this case,
deactivate ANC.
• If unusual (whistling or beeping) noise occurs, take the head-
phones off and put them on again. Make sure that the ear cups
properly fit around your ears.
• To avoid loud, unusual (whistling or beeping) noise and to ensure
proper noise cancellation, do not cover the microphone openings
of the active noise cancellation circuitry located on the outside of
the ear cups.
Activating/deactivating the active noise
cancellation ANC
To activate the active noise cancellation ANC:
▷ Slide the ANC switch to the position:
– “I” (middle switch position): adjustable ANC mode “USER” (>
23);
– “II” (lower switch position): maximum ANC mode “MAX”.
To deactivate the active noise cancellation ANC:
▷ Slide the ANC switch to the upper position “0”.
