Absolutely horrible audio on 3 C 425 and the C 101. Went to upgrade from my Blink cameras to this and I cannot believe how poor this is! I have reset, raised mic volume. Sounds like poor noise suppression. Static sound on all cameras when idle and muffled underwater sound voice, No obstruction, clear path for audio.    I need the audio quality as well as the Blink camereas. Maybe just return them?
