The effect of noise canceling is not sufficient.

  • Make sure that the noise canceling function is turned on.
  • Adjust the headset into a comfortable position.
  • The noise canceling function is effective in low frequency ranges such as airplanes, trains, offices, near air-conditioning, and is not as effective for higher frequencies, such as human voices.
  • Check that the Adaptive Sound Control is turned off.
    Check the setting of the Adaptive Sound Control on the “Sony | Headphones Connect” app. When the Adaptive Sound Control is turned on, the noise canceling function may become insufficient.
