Notes on Using the Noise Canceling Headphones
<Noise canceling headphones supplied models>

• The noise canceling function does not work on sound output through speakers, standard headphones, and devices via BLUETOOTH communication.

• The noise canceling function is less effective unless you properly wear the noise canceling headphones. Be sure to fit the headphones snugly into your ears by replacing the earbuds or adjusting the position of the headphones.

• The noise canceling function is to mainly reduce low-frequency noise in the ambient environment but not high-frequency noise.
  Nor is it to implement a 100% noise-free audio environment.

• Do not cover the built-in microphones (1) on the noise canceling headphones with your hands, etc., as it may cause the microphone directivity function to be less effective.

• You may hear a slight hissing noise while the noise canceling function is enabled. This is the operating noise of the noise canceling function and does not indicate a malfunction.

• You may feel that the noise canceling function is less effective or that ambient noise is even louder, depending on the type of noise or the degree of quietness in your environment.
  In such a case, disable the noise canceling function.

• Use of a mobile phone may cause radio interference to the noise canceling headphones. When using the headphones, keep mobile phones away from the headphones.

• Be sure to take off the noise canceling headphones from your ears before plugging or unplugging the headphones.
  Plugging or unplugging the headphones generates noise. This is normal and does not indicate a malfunction.

• If you configure the noise canceling headphones settings to pick up sounds using the built-in microphones on the noise canceling headphones and output them through the headphones, the sound will be amplified. Be careful of the volume when changing the settings.

• In certain situations, such as when ambient noise is loud, the microphone directivity function may be less effective or the volume level of the noise may fluctuate at short intervals.

• If the earbuds do not fit in your ears, you may not hear the bass sound. To enjoy better quality sound, fit the earbuds snugly into your ears by adjusting their position or pushing them deep into the ears.
  A pair of medium-size earbuds is attached to the headphones at the time of delivery. If you feel that the earbuds do not fit in your ears, replace them with an extra pair in small or large size.
