Here are pictures of how it fits over the popular Sony ECM-CS3 microphone. Struggles, it fits the mic well and is very snug. I will definitely not accidentally fall. I fitted a Sony ECM-CS3 to my car's rear bumper with these end caps to capture exhaust noise during trackdays and I am very happy with the results! Haven't tried just using the mic without those muffs in the same spot to see if they make a difference, but for the price I'd rather have one just in case. Also protects the mic from dirt etc. I use a zip tie around the mic and tape over the zip tie to secure the mic to the car.
