this mic is not that great at all. it picks up a lot of background noise and my personal phone camera does almost the same exact quality you get what you pay for on this one.
i'm a sound engineer with years of audio recording and editing experience. bought these as a cheaper alternative to the rode for my youtube channel content. they charged up quick and linked to the receiver immediately.i ran some tests with it clipped to my collar in a quite room and stood 10 ft. away from camera to record. samsung s21+ recognized the microphone immediately and alerted me audio was being recorded through the usb port upon pressing record. receiver picks up audio level sufficiently.the audio quality is on par with the price point i'd say... i've recorded with top teir microphones before and these sound like you're speaking through a landline phone. i will try to edit the frequencies in post production to see if it's usable.
