When the volume reaches the maximum or minimum, an alarm sounds.
Note
In the factory settings, you cannot adjust the volume on the headset. Adjust the volume on the connected device. If you are
unable to adjust the volume on the connected device, install the “Sony | Headphones Connect” smartphone app and adjust the
volume in the app.
If the communication condition is poor, the Bluetooth device may react incorrectly to the operation on the headset.
The available operations may vary depending on the connected device, the music software, or app used. In some cases, it may
operate differently or may not work even when the operations described above are performed.
