Set of four Waterproof Acoustic Vents for the AudioMoth IPX7 Case

Acoustic Vents work well

I performed a detailed test of the acoustic loss through these vents and they performed very well with less than 5 dB of loss across the human acoustic spectrum. This compares favorably to that available from other vent manufacturers.

Good vents but overexpensive shipping

Good product but shipping costs of 40 $ are overexpensive! Please adjust.
