IMPORTANT NOTE:
PLEASE READ THIS !!!!
This is a noise canceling microphone:
Don’t forget the lip guard is there to remind you of the close spacing required. To best describe the spacing,I would say your upper lip touches the rubber guard and bottom lip should almost drag the screen when talking. Take this mic away even 1″ or tilt sideways from your mouth and 70% of your audio is GONE !!!
