This cardioid polar mic offers directional audio capture, adjustable gain and filtering, and broad device compatibility for videographers, YouTubers, and sound recordists. It has a fashionable metal appearance. The built-in LED light indicates battery levels so that you can see directly if it is on working status. The flexible cable with max length of 90cm will enable you to hand-hold the microphone while you are recording and expand the range of application. It can be easily mounted onto your camera, as well as other devices with a 3.5mm mic-level input jack and standard hot shoe. We all know that the function of the built-in microphone of a camera is limited and can't avoid bad effects such as wind noise as it picks up sound from all directions. However, with the help of this Cardioid polar pattern microphone, you may not need to worry about this. A foam windscreen is included which helps reduce noise caused by wind or drafts from air conditioners.
