How does the noise cancelling microphone work on my Jabra headset?
A noise cancelling microphone filters out unwanted background noise. It does so by differentiating between sounds that come from nearby sources such as the mouth, and sounds that come from further away, which are then significantly reduced or eliminated. Therefore, it is important that you position the noise cancelling microphone close to your mouth - no further away than 1 to 2 finger widths (½-1 inch/12-24 mm), if the design of the microphone boom arm allows for this position.
