Functions for a phone call

The available functions may vary depending on the smartphone or mobile phone.

Depending on the connected device or the application you are using, the functions may not work properly even if you try to operate them with the headset.

Refer to the operating instructions supplied with the smartphone or mobile phone.


You can use either the left or right headset unit to perform the following operations.

When only one headset unit is worn in your ear, operate the headset unit that is worn.
