Connecting the headset to 2 Android smartphones (multipoint connection)

Usually, when you connect the headset to a smartphone, both the music playback function and the phone call function are connected simultaneously.

To make a multipoint connection using 2 smartphones to use one for listening to music and the other for making phone calls, set up to connect to only one function by operating the smartphone.

  1. Pair the headset with both smartphones, respectively.
  2. Operate one of the smartphones to establish a Bluetooth connection with the headset.
  3. Operate the smartphone connected to the headset, uncheck either [Call audio] (HFP) or [Media audio] (A2DP).

    Operation example: For connecting only through media audio (A2DP)

    Touch [Settings] - [Device connection] - [Bluetooth] - the setting icon next to [WH-CH710N].

    On the [Paired devices] screen, uncheck [Call audio].

  4. Operate the smartphone to terminate the Bluetooth connection.
  5. Operate the other smartphone to establish a Bluetooth connection with the headset.
  6. In the same way, uncheck the function that you did not uncheck in step 3.
  7. Operate the first smartphone to establish a Bluetooth connection with the headset.

    Both smartphones are connected to the headset with only one function enabled.


  • The operation above is an example. For more details, refer to the operating instructions supplied with the Android smartphone.


  • When using multipoint connection, the remaining battery charge of the headset will not be correctly displayed on the screen of the device that is connected for listening to music (A2DP).
  • When 2 Bluetooth devices have already connected to the WH-CH710N in a multipoint connection, and one is used for music playback (A2DP connection) and the other is used for calls (HFP/HSP connection), another NFC-compatible Bluetooth device cannot connect via Bluetooth connection with one-touch (NFC) even if you touch it with the WH-CH710N. In this case, disconnect one of the already connected Bluetooth devices and touch the Bluetooth device you want to connect with WH-CH710N again.
