^ i always wondered whether it would affect the sound if you have some foam in between there while filming, so i never bothered to do that and i also was way less worried about a board hitting the mic compared to like something happening while stored in the backpack.
funny thing is, once we were visiting a homie in his city to skate and had some drinks while at it. then after the session we went into some kind of beer garden and had some more. we then drunkenly bombed some hill and while pretty drunk i slammed with my camera backpack on against some parking car. this caused the microphone to snap and its ribbon cable broke because i had not yet used this put-in-foam-when-in-storage method. i was pretty mad at myself as we - same crew - were going to fly to barcelona some weeks afterwards and i was worried that we would not be able to film properly. shout out to the ebay legend in canada who quickly sent me one across the pond for a very solid price, i replaced the broken one and we were able to film some great clips in 10 days of barcelona (with sound!). this was in 2016, man - time flies.
