With a DJI microphone, you can make videos with bright and clear sound. You connect the microphone to your smartphone or camera and record audio right away. This is useful when you're interviewing someone or recording content for social media, for example. Choose a set with a charging case if you often make long recordings. You can wirelessly charge the microphones and receiver in the case. Only recording yourself? A single set suits you. This contains 1 microphone and 1 receiver.
