While you can connect the Wireless GO II receiver to your mobile device using either an analog or USB method to utilize it as a microphone for audio recording, it's important to note that the Wireless GO II cannot be used as a microphone for online communication apps like Zoom or MS Teams on mobile devices.
The limitation arises from the fact that the mobile app versions of these communication apps do not provide options to select microphone (input) or speaker (output) settings as available on computer versions. As a result, when using the mobile app, both input and output are automatically routed to the Wireless GO II. However, since the Wireless GO II doesn't function as a speaker, you won't be able to hear the recipients of your calls.
