Low sound quality

  • Turn down the volume of the connected device if it is too loud.
  • Keep the headset away from microwave ovens, Wi-Fi devices, etc.
  • Bring the headset closer to the Bluetooth device. Remove any obstacles between the headset and the Bluetooth device.
  • Keep the headset away from a TV.
  • Switch the Bluetooth connection to A2DP by operating the Bluetooth device when HFP or HSP is set.
  • If you connect a device with a built-in radio or tuner to the headset, broadcasts may not be received or the sensitivity may be reduced. Move the headset away from the connected device and try again.
  • If the headset connects to the previously connected Bluetooth device, the headset may only establish the HFP/HSP Bluetooth connection when it is turned on. Use the Bluetooth device to connect via an A2DP Bluetooth connection.
  • When listening to music from a computer on the headset, the sound quality may be poor (e.g., difficult to hear the singer’s voice, etc.) for the first few seconds after a connection is established.
    This is due to the computer specifications (priority on stable connection at the start of transmission and then switches to priority on sound quality several seconds later) and is not a headset malfunction. If the sound quality does not improve after a few seconds, press the (play) button on the headset once during playback. Or you can use the computer to establish an A2DP connection. As for the operations on your Bluetooth device, refer to the operating instructions supplied with the device.
