Cannot hear a person on a call.

  • Check that both the headset and the connected device (i.e., smartphone) are turned on.
  • Turn up the volume of the connected device if it is too low.
  • Check the audio settings of the Bluetooth device to make sure the sound is output to the headset during a call.
  • Use the Bluetooth device to reestablish the connection. Select HFP or HSP for the profile.
  • While listening to music with the headset, stop playback and tap the touch sensor twice quickly on the left or right unit to respond to an incoming call.
