Hint
When receiving a call by operating smartphones or mobile phones, some smartphones or mobile phones receive a call with the
phone instead of the headset. With an HFP or HSP connection, switch the call to the headset by holding your finger to the touch
sensor on the left or right unit of the headset for about 2 seconds, or by using your smartphone or mobile phone.
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 hands-free calls even when you wear only one unit of the headset. When an incoming call arrives, answer the
call using the headset unit you are wearing. If you wear the other unit while you are talking with only one unit, you can talk with
both units.
Note
Depending on the smartphone or mobile phone, when an incoming call arrives while you are listening to music, playback may not
resume automatically even if you finish the call.
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 microphones (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.
Even when the volume adjustment function has been assigned to the touch sensor, you cannot adjust the volume on the headset
during a call. 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.

The headset may not be connected with the smartphone or mobile phone over HFP or HSP. Check the
connection status on the smartphone or mobile phone.
If playback does not pause automatically, operate the headset to pause playback.
Operate the smartphone or mobile phone to adjust the volume.

When you finish talking, tap the touch sensor on the left or right unit of the headset twice (with an interval
of about 0.3 seconds) to end the call.
If you received a call during music playback, music playback resumes automatically after ending the call.
