This microphone is great for a plug-n-play, compact, lightweight sound enhancer. What it does is amplify all the sounds around you. I've found it is ideal for use with a bird call identification app such as Merlin. For whatever reason, boosting both the bird calls and background noise causes the app to be much more likely to identify a bird. It also is small and connects directly without a cord, so you can use only one hand to hold the phone and mic, making it easier to use a camera or binoculars at the same time.The only reason it is not 5 stars is because of the wind noise and sound quality. The provided wind screen is going to fall off and disappear quickly even if you use a rubber band. With or without the wind screen, you will get a lot of wind and background noise. This is not a professional microphone for making a high quality recording. If the goal is to make a professional video or audio recording, then a larger, more expensive microphone would serve that purpose better.
