As these microphones are powered by a battery, you'll need to make sure they are switched on with a illuminated LED before use with a camera or audio recorder.
If you don't see a LED on the microphone or if it doesn't turn on, try using different alkaline batteries to see does turn on.
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.
