Wireless Noise Canceling Stereo Headset
WH-CH720N
What is noise canceling?
The noise canceling function generates antiphase sound against outside surrounding noises (such as noises in vehicles
or noises from air conditioners indoors) to reduce the surrounding noises by canceling them out.
Note
Depending on the type of noise or if it is used in a very quiet environment, you may not feel the effect of noise canceling, or you
may feel that some noise is increased.
When you are wearing the headset, depending on how you wear the headset, the effect of noise canceling may be decreased or
a beeping sound (feedback) may be heard. In this case, take off the headset and put it on again.
The noise canceling function works primarily on noise in the low frequency band such as vehicles and air conditioning. While
noise is reduced, it is not completely canceled.
When you use the headset in a car or a bus, noise may occur depending on street conditions.
Mobile phones may cause interference and noise. Should this occur, move the headset further away from the mobile phone.
Do not cover the microphones on the left and right units of the headset with your hand, etc. If they are covered, the effect of the
noise canceling or the Ambient Sound Mode may not perform properly, or a beeping sound (feedback) may occur. If any of this is
the case, remove your hands, etc. from the left and right microphones.
