Making a call

You can enjoy a hands-free call with a smartphone or mobile phone that supports the Bluetooth profile HFP (Hands-free Profile) or HSP (Headset Profile), via Bluetooth connection.

  • If your smartphone or mobile phone supports both HFP and HSP, set it to HFP.
  • The operation may vary depending on the smartphone or mobile phone. Refer to the operating instructions supplied with 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 touch sensors.
  1. Connect the headset to a smartphone/mobile phone via Bluetooth connection.
  2. Operate your smartphone or mobile phone to make a call.

    When you make a call, the dial tone is heard from the headset.

    If you make a call while you are listening to music, playback pauses.

    You can talk using the microphones on the headset.

    • Use your smartphone or mobile phone to switch from the call device to the headset, or hold your finger to the touch sensor on either the left or right headset unit for about 2 seconds.

  3. Operate the smartphone or mobile phone to adjust the volume.
  4. 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 made a call during music playback, music playback resumes automatically after ending the call.


  • 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. If you wear the other unit while you are talking with only one unit, you can talk with both units.


  • 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.
