Headset and microphone setup

For the best performance, use an external headset and microphone when making calls. Our recommended headsets can be found here.

Audio settings are configured from within the Close.io application by using the Phone Settings popover.

Please Note: Headsets being used for the first time may need device drivers to be installed before they will appear in Close.io

Why Close.io wasn't able to get access to my microphone?

Common reasons for this include:

Another application or browser tab is using your microphone already. Check for other browser tabs (Google Hangout, Skype Web, appear.in, etc)
Your anti-virus software is protecting an audio stream coming from sound recording devices. If you are a Kaspersky customer, please, read this link and check if your problem can be fixed
Your microphone is disconnected and your computer has no built-in microphone
You are using Windows 10 and your internal microphone is not working after the upgrade. Check if this link is a possible solution for you
