Using the earbuds

Information on active noise cancellation
ANC
Due to the wearing style in the ear canal, the earbuds provide effec-
tive passive isolation from ambient noise.
In addition, the earbuds have an active noise cancellation (ANC)
function, which allows you to reduce ambient noise to a minimum.
This feed forward system with one microphone per earbud is espe
-
cially effective at reducing low-frequency noise. A possible feeling of
pressure on the ears and the slight ANC noise (in very quiet environ
-
ments) is avoided with this system.
Even when ANC is activated, your headphones’ sound quality is
always at its best.
If you want to create a quiet space in a noisy environment, you can
simply use the earbuds as noise protection by using ANC.
Notes on active noise cancellation
• Continuous low-frequency noise, such as motor or fan noise, is
particularly well suppressed.
• Speech or high-frequency noise is significantly reduced, but can
remain perceptible.
• If unusual (whistling or beeping) noise occurs, take the head-
phones off and put them on again. Make sure that the earbuds
properly fit in your ears and make a good seal with the ear canal.
• 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.
• With active noise cancellation ANC activated, the battery life of
the earbuds is reduced.
