What is Noise-cancellation?

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


What can I expect from Noise-cancellation technology?

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

However, remember the following:

  • The noise cancelling effect may not be pronounced in a tranquil environment, or some sound may be heard. If there is little ambient noise, it is even advisable not to switch on the NC function, as it needs ambient input to function optimally.
  • Depending on how you wear the headset, the noise cancelling effect may vary, or a beeping sound (howling) may occur. In these cases, take off the headset and put it on again.
  • The noise cancelling function works for noise in the low-frequency band primarily (train, aeroplane, engine noise). Although noise is reduced, it is not cancelled altogether.
  • When you use the headset in a train or a car, noise may occur depending on environmental conditions. It is not advisable to wear noise-cancellation headphones while driving, as taking notice of traffic sounds is essential for your safety.
  • Mobile phones may cause interference and noise. Should this occur, locate the headset further away from the mobile phone.
  • Do not cover the microphones. The noise cancelling 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.
