Blackwire 500 Series: Cannot Hear Caller

I cannot hear the caller when I answer a call on my Blackwire C510/C520/C510-M/C520-M. What is the reason?
  • Listening volume is too low. Press the volume up (+) button to increase the volume on the headset.
  • The headset may not be set as default audio device. Set the headset as default audio device on your computer. Click here to learn more about how to set your headset as default audio device in your computer.
