What is Noise-Cancellation and what can I expect?

    What is Noise-cancellation?

    The noise canceling circuit senses outside noise with built-in microphones and sends an equal-but-opposite canceling signal to the headset. By producing this countersignal, your headphones block a large part of external sound sources. This is called sound compensation.


    How does sound compensation work?

    Noise cancellation works independently for the left and the right channel. Sound compensation works predictively, providing inverse signals to the speakers who will then eliminate the noise. Because it is a predictive system, rapidly changing sounds or air pressures are compensated differently depending on how they reach the right or left noise-cancellation microphone. In other words, sound compensation is customized and can impact the output of each independent side.


    What can I expect from Noise-cancellation technology?

    Noise cancellation offers an enhanced listening experience by canceling out interfering external sounds.


    • The noise canceling effect may not be pronounced in a tranquil environment, or some sound may be heard. If there's little ambient noise, it's advisable not to switch on the noise canceling function, as it needs ambient input to function optimally.
    • Noise cancellation doesn't transfer during telephone calls. Although it protects the headphones user from the surrounding noise, it does not apply to the receiver of the call, they will potentially hear background noise.
    • Depending on how you wear the headset, the noise canceling effect may vary, or a beeping sound (howling) may occur. In these cases, take off the headset and put it on again.
    • The noise canceling function works for noise in the low-frequency band primarily (train, airplane, engine noise). Although noise is reduced, it is not canceled altogether.
    • If you use the headset in a train or a car, noise may occur depending on environmental conditions. It's not advisable to wear noise-cancellation headphones while driving, as taking notice of traffic sounds is essential for your safety.
    • Mobile devices may cause interference and noise. If this occurs, move your mobile devices away from the headphones.
    • Don't cover the microphones. The noise canceling function or the Ambient Sound Mode may not work optimally, or a beeping sound (howling) may occur. In these cases, take your hands off the headset microphones.
