Notes for using the noise canceling function

  • If the earbuds do not fit your ears, the effect of the noise canceling function may be compromised. Adjust the earbuds to a position where they fit well, and place them snugly in your ears.

  • Rubbing noises may occur while wearing headphones. This is not a malfunction.
  • The noise canceling function mainly reduces noise in low frequency bands and has no effect on noise in higher frequency bands. Note that it does not cancel all sounds.
  • Do not cover the microphone part () of the headphones with your hands or other objects. Doing so may compromise the noise canceling effect.

  • You may hear a slight hissing noise when the noise canceling function is active. This is operational noise of the noise canceling function and not a malfunction.
  • You may feel that the noise canceling function is not working or noise is louder in quiet places or with certain types of noises. In this case, deactivate the noise canceling function.
  • Mobile phones or smartphones may cause noise. If this occurs, keep your Walkman away from these devices.
  • Make sure to remove the headphones from your ears before you connect or disconnect the headphones from your Walkman. If the headphones are connected or disconnected from the Walkman during playback or while the noise canceling function is active, noise may be generated. This is not a malfunction.
  • When changing the [Noise Canceling: On/Off] setting, a switching sound will be generated. This sound is generated by switching of the noise canceling circuit, and is not a malfunction.
