Just purchased 2 Redhead Windscreens from www.redheadwindscreens.com. I feel like I made our Zoom H4N recorder a troll doll but so far so good. I decided to go with Red and Gunmetal. The video above provides a good estimation of protecting against cross winds. However, I noticed that direct wind can still be picked up by the recording. I think its because of our studio headphones we use with it. The H4N can pick up nearly everything around it if you want it to.
