Wireless Noise Canceling Stereo Headset

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 noise canceling effects, or you

may feel that some noise is increased.

When you are wearing the headset, depending on how you wear the headset, the noise canceling effects 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 call microphone (A) on the left unit of the headset and the noise canceling function microphones (B) 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 be obtained, or a beeping sound (feedback) may occur. If any of this is the case, remove your hands, etc. from the

left and right microphones.
