Using a microphone with your phone: 

Before captioning videos: 

• Get as close to the sound source as possible 
• Connect the mic before launching the app 

Types of phone mics: 

1. 3.5mm headphone jack: You can connect any 3.5mm cable with a cable to your phone, if your phone still offers a 3.5 mm or mini-jack input option. 

2. microUSB: The change from microUSB to USB-C as the preferred “power port“ coincided with the trend to drop the headphone jack. 

3. USB-C 

Note: quite a few phone makers include a USB-C to 3.5mm-adapter
