NOTE: The Noise Canceling function is most effective for low frequency (bass) noise, such noise made by vehicles or air conditioning, but not all sounds can be completely canceled. Follow these steps if you feel that noise canceling function is insufficient:
Step 1: Make sure that the Noise Canceling function is turned on.
Follow one of these procedures to make sure that the Noise Canceling function is turned on:
Place both units of the headphones in the charging case, leave them for a few seconds, and then remove them from the charging case. Once removed from the charging case, the Noise Canceling function will be on.
While wearing the headphones, tap the L side touch sensor until you hear the voice guidance Noise canceling. In the default setting, you can switch the Noise Canceling function and Ambient Sound by tapping the L side touch sensor.NOTES:
If the headphones do not switch to the Noise Canceling function, try tapping once, more quickly (about 0.3 second). If the contact time between the touch sensor and finger is too long, the mode switches to Quick Attention mode and it does not switch to the Noise Canceling function.
If you follow the appropriate procedure and cannot switch the Noise Canceling function by tapping the L side touch sensor, the assignment of the touch sensor or button may be set to another function, such as Google Assistant. If this is the case, change the setting back to the Noise Canceling function using the Sony | Headphones Connect app. Related Article: The Google Assistant unintentionally starts when I try to switch the Noise Canceling and Ambient Sound Mode functions.
