You cannot adjust the volume during a call 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 | Music Center” smartphone app and adjust the volume in the app.
The headset volume during a call and during music playback can be independently adjusted. Changing the call volume does not
change the volume of music playback and vice versa.
You can also enjoy a hands-free call by wearing only one unit of the headset. If you wear the other unit while you are talking with
only one unit, you can talk with both units.
Note
Use a smartphone or mobile phone at least 50 cm (19.69 in.) away from the headset. Noise may result if the smartphone or
mobile phone is too close to the headset.
Your voice will be heard from the headset through the headset’s microphone (Sidetone function). In this case, ambient sounds or
the sounds of the headset operation may be heard through the headset, but this is not a malfunction.
