A microphone, whether dynamic or condenser-type, is any type of air movement that occurs through a pure sound event without modification. Current, headwind or breeze caused by weather conditions, but also a simple air stream that forms around the microphone can cause a bubbling that would ruin the audio recording. Even breathing of the speaker near the microphone can cause crackles. The windbreaker absorbs that breeze and ensures that it does not enter the microphone capsule. For outdoor recordings, a synthetic leather windbreaker is especially recommended that keeps the usual wind sounds away from the microphone.
