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 headset.
  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.

    If no dial tone is heard via the headset

    Use your smartphone or mobile phone to switch from the call device to the headset, or press and hold the button 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, press the button on the left or right unit of the headset 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. Even if you change the volume during a call, the volume of music playback does not change.
  • You can also enjoy hands-free calls even when you are using only one unit of the headset. If you remove the other unit of the headset from the charging case 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 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.
  • You cannot adjust the volume during a call on the headset. Adjust the volume on the connected device.
  • When you are using only one unit of the headset, be sure to set the other unit in the charging case.
