Go to the Audio Settings on the web app.
A list of available devices should become available. Look for the brand of your headset and select it.
In this example, we are using Logitech:
Make sure you select the same headset to be used as microphone and speaker.
If you don't see yours, close the browser, unplug it and plug it back, open the browser and repeat the steps above.
Save and Close and your new headset will be used the next time you call.
Note 1: if the headset is not connected while you receive or make a call, Toky will use the built-in microphone and speaker instead.
Note 2: if you're encountering audio issues, please check this tutorial.
