As this microphone requires plug-in power (1.5-5V) from the connected device, make sure your camera or audio recorder is supplying plug-in power. Please refer your camera or audio recorder's manual to make sure its enabled.
These microphones are primarily designed to be connected to cameras and audio recorders. However, you can connect them to mobile devices using a TRS-TRRS adaptor such as the SC4 or SC7.
These adaptors will work with virtually every mobile device however not every computer/laptop.
When using these microphones with mobile devices, we always recommend using official USB-C/ Lightning to 3.5mm adapters to connect them to mobile devices. Generic 3rd party 3.5mm adapters may not work as intend with microphones.
