Receiving a call

You can talk on the phone hands-free via a Bluetooth connection on a smartphone that supports the following Bluetooth profiles.

  • HFP (Hands-free Profile)
  • HSP (Headset Profile)


  • If your smartphone supports both HFP and HSP, set it to HFP.
  • The operating procedure may vary depending on the smartphone. Refer to the operating instructions supplied with the smartphone.
  • 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.

Ring tone

When you receive an incoming call, a ring tone will be heard from the headset.

You will hear either of following ring tones, depending on your smartphone.

  • Ring tone set on the headset
  • Ring tone set on the smartphone
  • Ring tone only for a Bluetooth connection set on the smartphone
  1. Connect the headset to a smartphone via a Bluetooth connection beforehand.
  2. When you hear a ring tone, tap the touch sensor on the left or right headset unit twice quickly with an interval of about 0.3 seconds to receive the call.

    Sound will be heard from the headset.

    When you receive an incoming call while listening to music, playback pauses automatically and a ring tone will be heard from the headset.

    If playback is not paused, operate the headset to pause playback.

    You can talk using the microphones (A) on the left and right headset units.

    If no ring tone is heard via the headset

    The headset may not be connected with the smartphone over HFP or HSP. Check the connection status on the smartphone.

  3. Operate the smartphone to adjust the volume.
  4. When you have finished your call, tap the touch sensor on the left or right headset unit twice quickly with an interval of about 0.3 seconds between taps to end the call.

    If you received a call during music playback, music playback resumes automatically after ending the call.

Hint

  • When receiving a call when using a smartphone, some smartphones may receive a call on the phone instead of the headset. When using HFP connection, transfer the call to the headset by using your smartphone.
  • The volume can also be adjusted on the “Sound Connect” app. 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 talk hands-free even when you are wearing only one headset unit. When you receive an incoming call, answer the call using the headset unit you are wearing. If you put the other headset unit into the other ear while you are talking with only one headset unit, you can talk with both headset units.

Note

  • Depending on the connected device or playback application you are using, playback may not pause even when you receive an incoming call while playing back music. When you receive an incoming call while playing back music, playback may not resume automatically even if you finish the call.
  • Use the smartphone at least 50 cm (1.6 ft) away from the headset. Noise may result if the smartphone is too close to the headset.
  • In order to make it easier for you to hear your own voice during a phone call, the microphones work to capture ambient sounds (Sidetone function). If your voice is too loud or the sounds in your surroundings are bothering you, you can change the setting with the “Sound Connect” app. Turn off [Capture Voice During a Phone Call].
  • The volume during calls cannot be adjusted with the headset. Adjust the volume on the connected device or the “Sound Connect” app.
  • When you are using only one headset unit, be sure to set the other headset unit into the charging case.
  • Depending on the caller’s voice characteristics or the ambient environmental noises, the audio signal processing that is mounted on the headset may not work well and the call sound quality may be reduced.
