How to use the noise canceling function
By using the noise canceling function, you can suppress surrounding noise and concentrate on the music. Effective in crowded places or places with loud environmental sounds.
1) Remove the headset from the charging case
The power will turn on automatically and the device will be connected to the device that has Bluetooth settings. When using the headset for the first time or immediately after initializing the headset, the noise canceling function is automatically turned on when the headset is turned on. From the second time onwards, the previous settings are retained.
2) Press the button on the L side to switch the noise canceling function.
Each time you press the button, you can switch between the external sound capture function and noise canceling.
A notification tone will sound from both headsets at the same time.
important point
・If you do not use the included earpiece, the noise canceling function will not be fully effective.
・If the headset is not securely attached to your ears, the noise canceling function may not work properly.
・Do not cover the microphones of the left and right headsets with your hands. The noise canceling function and external sound intake function may become ineffective, or a beeping sound (howling) may occur. In this case, remove your hands from the left and right microphones.
Depending on the quiet location or the type of noise, you may not feel the noise canceling effect or you may feel that the noise has become louder.
The noise canceling function is most effective against noises in the low frequency range, such as those from vehicles and air conditioning. Not all sounds are canceled out.
Volume adjustment
If you change the button function to "Volume Control" in the Sony Headphones Connect app, you can adjust the volume using the button to which the function is assigned.
increase volume
Pressing the button once during playback increases the volume by one step.
reduce volume
If you hold down the button during playback, the volume will decrease continuously. Release the button when the volume reaches a suitable level.
A warning tone will sound when the volume reaches maximum or minimum.
important point
The volume cannot be adjusted using the headset in its default state. If you do not change the button function to "Volume Control" using the Sony Headphones Connect app, you will need to adjust the volume on the connected device. You can also adjust it on the app.
When connected to an iPhone, pressing and holding the button on the R side may activate Siri.
