Help Guide Wireless Noise Canceling Stereo Headset WF-SP700N What is noise canceling? The noise canceling circuit actually senses outside noise with built-in microphones and sends an equal-but-opposite canceling signal to the headset. Note The noise canceling effect may not be pronounced in a very quiet environment, or some noise may be heard. 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 primarily for noise in the low frequency band. Although noise is reduced, it is not canceled completely. When you use the headset in a train or a car, noise may occur depending on street conditions. Mobile phones may cause interference and noise. Should this occur, locate the headset further away from the mobile phone. Do not cover the microphones (A) of the headset with your hands. The noise canceling function or the Ambient Sound Mode may not work properly, or a beeping sound (howling) may occur. In these cases, take your hands off of the microphones of the headset.

canceling signal to the headset.

The noise canceling effect may not be pronounced in a very quiet environment, or some noise may be heard.
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 primarily for noise in the low frequency band. Although noise is reduced, it is not canceled
completely.
When you use the headset in a train or a car, noise may occur depending on street conditions.
Mobile phones may cause interference and noise. Should this occur, locate the headset further away from the mobile phone.
Do not cover the microphones (A) of the headset with your hands. The noise canceling function or the Ambient Sound Mode may
not work properly, or a beeping sound (howling) may occur. In these cases, take your hands off of the microphones of the
