Precautions for using different devices:

1. Speaker: Please adjust the receiver to light blue light mode to avoid echoes and provide strong noise reduction.

2. Computer: It is recommended to use it with a USB plug into the computer. After our testing, some old computers may not be able to use the microphone function due to inconsistent compatibility with the 3.5mm jack, and other types of adapter cables need to be connected for use, which is very troublesome. So we suggest using our OTG audio cable and USB, plugging it into the computer and waiting for a few seconds to automatically install the driver, which can be used without manual operation.

3. Camera: Our microphone supports stereo sound, but does not distinguish between left and right channels.

4. Mobile phone: It is recommended to use it with our OTG audio cable and IOS adapter. If the battery of the phone or receiver is low during use, we can plug in the charger through our OTG audio cable to charge the phone and receiver.
