Due to its closed design, the headphones offer effective passive isolation 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 (> Deactivating Bluetooth/activating the flight mode).
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 particularly 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 headphones 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.
