They worked and canceled out the wind in an interview I did outside with a bike rider I rode next to riding down the road… so there was lots of wind noise but it almost all canceled out. Impressive at the default level 1.I’m picky but I spent years in broadcasting with professional microphones in radio and television … the frequency response isn’t as good as I would expect from my iPhone microphone which is excellent. These mics are at the lower end of the wireless microphone price points and it shows with a bit of a compromise in audio quality.When you play it back you become acclimated to the thinner slightly tin like sounding audio but if you’re just doing voice and not music like I do it seems adequate.They were better than other wireless mics I have tried that were in this price range.The batteries held up nicely for over an hour of use.It’s really great that you have two mics so that the interviewer and the interview subjects audio match.Nice that they sent you an extra set of clips because they’re plastic and not metal like professional grade mini Mics and that way you have two spares in case you break some going over a piece of large fabric or a zipper trying to clip them on to an interview subject.
