A:AnswerSorry, no idea. I use mine for audio recording on my computer. It connects to the computer through a standard USB cable and has no other source of power. It is also about 4 inches in diameter so it would be very conspicuous if you were using it to capture audio clandestinely. :)
A:AnswerDepends on how loud you are. U gotta test it out to see where it picks up your voice and where it doesn’t. I have mine abt 5-6 inches away from my face and it still picks up my voice. And if you’re recording a video, and it doesn’t pick up you’re voice as much, you can always edit and fix that
