How to set up the Cisco Headset 520 Series, from unboxing to a working test. It's a business headset: connect it by USB cable or dongle (or Bluetooth) and select it as the microphone and speaker in Teams, Zoom, Meet or your softphone.
Before you start: check the box
- Headset 521 or 522
- In-line USB adapter
What you need
- Ports on the Headset 520 Series: 3.5 mm plug plus in-line USB-A or USB-C controller.
- A computer with a free USB port (or the USB adapter in the box). Plug directly into the computer rather than through a hub where possible.
Step by step
-
Fit it. Adjust the headband and boom so the microphone sits about two fingers from the corner of your mouth.
-
Connect it. Connect the USB cable to the computer; it powers the Headset 520 Series. Plug straight into the computer rather than a hub where you can.
-
Set up USB mode. Connect the Headset 520 Series to the computer by USB. In Teams, Zoom or Meet, open the device settings and select the Headset 520 Series as the microphone and speaker.
-
Update the firmware. Update to the latest firmware before you go live. See Updating the firmware below.
-
Make a test call. Make a test call and ask the other side whether you're clear and at a good level; check mute sync between the headset and the app.
Updating the firmware
Update to the latest firmware before you go live, using the manufacturer's app or the device's settings.
- Don't unplug power or USB while an update runs.
- Close Teams, Zoom and other apps that use the device before updating it from a computer.
- In a big rollout, update one device first, make a test call, then roll out to everyone else.
